91097717 ÷ 372 
The aim is to understand the frequency of 372 in 91097717.

On to step 1:
372 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 372

Advancing to step 2:
When dividing 91 by 372, we get 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Append the next digit (0) from the dividend to 91 and continue with: 910 / 372

Going ahead to step 3:
If we divide 910 by 372, we get 2 and a remainder of 166.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 744 from 910, we get 166.
Append the next digit (9) from the dividend to 166 and continue with: 1669 / 372

Moving on to step 4:
372 goes into 1669 4 times with a remainder of 181.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 1488 away from 1669, we end up with 181.
Append the next digit (7) from the dividend to 181 and continue with: 1817 / 372

Step 5:
When dividing 1817 by 372, we get 4 with a remainder of 329.
Put 4 as the next digit of the answer. 
Result so far: 244.0
Deduct 1488 from 1817 and we're left with 329.
Bring next digit (7) of the dividend behind the 329 and repeat the process: 3297 / 372

Moving on to step 6:
372 goes into 3297 8 times with a remainder of 321.
Use 8 as the next digit of our solution. 
Result so far: 2448.0
Subtract 2976 from 3297 to get 321.
Grab the next digit (1) from the dividend, add it to 321, then carry on: 3211 / 372

Advancing to step 7:
The number 372 fits into 3211 8 times, leaving a remainder of 235.
Write down 8 as next digit of the result. 
Result so far: 24488.0
If we subtract 2976 from 3211, we get 235.
Include the next digit (7) from the dividend after 235, then repeat: 2357 / 372

Let's proceed to step 8:
When dividing 2357 by 372, we get 6 with a remainder of 125.
Record the quotient 6 as the next digit in the result. 
Result so far: 244886.0
Subtract 2232 from 2357 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
1250 divided by 372 is 3 with a remainder of 134.
Put 3 as the next digit of the answer. 
Result so far: 244886.3
Deduct 1116 from 1250 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 10:
372 can be fit into 1340 3 times, resulting in a remainder of 224.
The next digit of our result is 3. 
Result so far: 244886.33
The remainder is 224 after subtracting 1116 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Our division results in 244886.33 with a remaining 0.224.
