We look at the division of 97368871 by 938 
The aim is to understand the frequency of 938 in 97368871.

Step 1:
938 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 938

Moving on to step 2:
If we divide 97 by 938, we get 0 and a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Fetch the next digit (3) from the dividend, attach it to 97 and continue: 973 / 938

Advancing to step 3:
If we divide 973 by 938, we get 1 and a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 938 from 973, we get 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 938

Advancing to step 4:
938 goes into 356 0 times with a remainder of 356.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 356 and we're left with 356.
Include the next digit (8) from the dividend after 356, then repeat: 3568 / 938

On to step 5:
If we divide 3568 by 938, we get 3 and a remainder of 754.
Use 3 as the next digit of our solution. 
Result so far: 103.0
If we subtract 2814 from 3568, we get 754.
Grab the next digit (8) from the dividend, add it to 754, then carry on: 7548 / 938

Advancing to step 6:
7548 divided by 938 is 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 1038.0
The remainder is 44 after subtracting 7504 from 7548.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 938

Going ahead to step 7:
447 divided by 938 is 0 with a remainder of 447.
The next digit of our result is 0. 
Result so far: 10380.0
Deduct 0 from 447 and we're left with 447.
Include the next digit (1) from the dividend after 447, then repeat: 4471 / 938

Advancing to step 8:
4471 divided by 938 is 4 with a remainder of 719.
Record the quotient 4 as the next digit in the result. 
Result so far: 103804.0
Deduct 3752 from 4471 and we're left with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Step 9:
The number 938 fits into 7190 7 times, leaving a remainder of 624.
Use 7 as the next digit of our solution. 
Result so far: 103804.7
The remainder is 624 after subtracting 6566 from 7190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 10:
When dividing 6240 by 938, we get 6 with a remainder of 612.
The next digit of our result is 6. 
Result so far: 103804.76
The remainder is 612 after subtracting 5628 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Going ahead to step 11:
938 can be fit into 6120 6 times, resulting in a remainder of 492.
The next digit of our result is 6. 
Result so far: 103804.766
If we take 5628 away from 6120, we end up with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

The final result is 103804.766 with a remainder of 0.0492.
