Let's divide 98591404 by 388
The aim is to understand the frequency of 388 in 98591404.

Moving on to step 1:
9 divided by 388 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 388

Step 2:
388 can be fit into 98 0 times, resulting in a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Take the next digit (5) from the dividend and append it to 98, then repeat: 985 / 388

Going ahead to step 3:
388 goes into 985 2 times with a remainder of 209.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 776 from 985 to get 209.
Grab the next digit (9) from the dividend, add it to 209, then carry on: 2099 / 388

Going ahead to step 4:
The number 388 fits into 2099 5 times, leaving a remainder of 159.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 1940 from 2099 and we're left with 159.
Append the next digit (1) from the dividend to 159 and continue with: 1591 / 388

Step 5:
388 can be fit into 1591 4 times, resulting in a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
If we take 1552 away from 1591, we end up with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 388

On to step 6:
394 divided by 388 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 2541.0
If we subtract 388 from 394, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 388

Going ahead to step 7:
388 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 25410.0
If we subtract 0 from 60, we get 60.
Grab the next digit (4) from the dividend, add it to 60, then carry on: 604 / 388

Advancing to step 8:
When dividing 604 by 388, we get 1 with a remainder of 216.
Record the quotient 1 as the next digit in the result. 
Result so far: 254101.0
Deduct 388 from 604 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 9:
2160 divided by 388 is 5 with a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 254101.5
If we subtract 1940 from 2160, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
388 goes into 2200 5 times with a remainder of 260.
Write down 5 as next digit of the result. 
Result so far: 254101.55
The remainder is 260 after subtracting 1940 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

After the division, we end up with 254101.55 and a remainder of 0.26.
