Let's divide 60699490 by 398
The aim is to understand the frequency of 398 in 60699490.

Step 1:
398 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 398

Advancing to step 2:
The number 398 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 398

Step 3:
398 can be fit into 606 1 times, resulting in a remainder of 208.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 398 away from 606, we end up with 208.
Fetch the next digit (9) from the dividend, attach it to 208 and continue: 2089 / 398

On to step 4:
398 goes into 2089 5 times with a remainder of 99.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 1990 away from 2089, we end up with 99.
Fetch the next digit (9) from the dividend, attach it to 99 and continue: 999 / 398

Step 5:
398 can be fit into 999 2 times, resulting in a remainder of 203.
The next digit of our result is 2. 
Result so far: 152.0
The remainder is 203 after subtracting 796 from 999.
Grab the next digit (4) from the dividend, add it to 203, then carry on: 2034 / 398

On to step 6:
2034 divided by 398 is 5 with a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 1525.0
If we subtract 1990 from 2034, we get 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 398

Going ahead to step 7:
398 goes into 449 1 times with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 15251.0
The remainder is 51 after subtracting 398 from 449.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 398

Moving on to step 8:
The number 398 fits into 510 1 times, leaving a remainder of 112.
Use 1 as the next digit of our solution. 
Result so far: 152511.0
Subtracting 398 from 510 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 9:
398 can be fit into 1120 2 times, resulting in a remainder of 324.
The number 2 becomes the next digit in our result. 
Result so far: 152511.2
The remainder is 324 after subtracting 796 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 10:
398 goes into 3240 8 times with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 152511.28
The remainder is 56 after subtracting 3184 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
398 can be fit into 560 1 times, resulting in a remainder of 162.
The next digit of our result is 1. 
Result so far: 152511.281
Subtract 398 from 560 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 12:
When dividing 1620 by 398, we get 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 152511.2814
If we take 1592 away from 1620, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
If we divide 280 by 398, we get 0 and a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 152511.2814
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 14:
398 can be fit into 2800 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 152511.281407
If we subtract 2786 from 2800, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 15:
140 divided by 398 is 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 152511.281407
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 16:
398 goes into 1400 3 times with a remainder of 206.
Write down 3 as next digit of the result. 
Result so far: 152511.28140703
Subtracting 1194 from 1400 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

The final outcome is 152511.28140703, with a leftover of 2.06e-07.
