We're dividing 74887655 by 398 
The aim is to understand the frequency of 398 in 74887655.

Going ahead to step 1:
398 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 398

Step 2:
When dividing 74 by 398, we get 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Take the next digit (8) from the dividend and append it to 74, then repeat: 748 / 398

Going ahead to step 3:
When dividing 748 by 398, we get 1 with a remainder of 350.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 398 from 748 and we're left with 350.
Fetch the next digit (8) from the dividend, attach it to 350 and continue: 3508 / 398

On to step 4:
398 goes into 3508 8 times with a remainder of 324.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 3184 from 3508 leaves us with 324.
Bring next digit (7) of the dividend behind the 324 and repeat the process: 3247 / 398

Moving on to step 5:
The number 398 fits into 3247 8 times, leaving a remainder of 63.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Subtract 3184 from 3247 to get 63.
Bring next digit (6) of the dividend behind the 63 and repeat the process: 636 / 398

Moving on to step 6:
398 goes into 636 1 times with a remainder of 238.
Use 1 as the next digit of our solution. 
Result so far: 1881.0
The remainder is 238 after subtracting 398 from 636.
Include the next digit (5) from the dividend after 238, then repeat: 2385 / 398

Going ahead to step 7:
398 goes into 2385 5 times with a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 18815.0
Subtracting 1990 from 2385 leaves us with 395.
Grab the next digit (5) from the dividend, add it to 395, then carry on: 3955 / 398

Advancing to step 8:
The number 398 fits into 3955 9 times, leaving a remainder of 373.
The number 9 becomes the next digit in our result. 
Result so far: 188159.0
The remainder is 373 after subtracting 3582 from 3955.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 9:
398 can be fit into 3730 9 times, resulting in a remainder of 148.
Put 9 as the next digit of the answer. 
Result so far: 188159.9
Deduct 3582 from 3730 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 10:
398 can be fit into 1480 3 times, resulting in a remainder of 286.
Record the quotient 3 as the next digit in the result. 
Result so far: 188159.93
Deduct 1194 from 1480 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 11:
The number 398 fits into 2860 7 times, leaving a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 188159.937
Subtracting 2786 from 2860 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 12:
398 can be fit into 740 1 times, resulting in a remainder of 342.
Write down 1 as next digit of the result. 
Result so far: 188159.9371
Subtracting 398 from 740 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 13:
When dividing 3420 by 398, we get 8 with a remainder of 236.
Use 8 as the next digit of our solution. 
Result so far: 188159.93718
Subtracting 3184 from 3420 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 14:
When dividing 2360 by 398, we get 5 with a remainder of 370.
Write down 5 as next digit of the result. 
Result so far: 188159.937185
Deduct 1990 from 2360 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 15:
When dividing 3700 by 398, we get 9 with a remainder of 118.
Use 9 as the next digit of our solution. 
Result so far: 188159.9371859
The remainder is 118 after subtracting 3582 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 16:
If we divide 1180 by 398, we get 2 and a remainder of 384.
The next digit of our result is 2. 
Result so far: 188159.93718592
Deduct 796 from 1180 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

In conclusion, the division gives 188159.93718592 with a balance of 3.84e-07.
