We look at the division of 91501136 by 372 
The aim is to understand the frequency of 372 in 91501136.

On to step 1:
The number 372 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 372

Going ahead to step 2:
When dividing 91 by 372, we get 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 372

Advancing to step 3:
372 can be fit into 915 2 times, resulting in a remainder of 171.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 744 from 915 to get 171.
Grab the next digit (0) from the dividend, add it to 171, then carry on: 1710 / 372

Advancing to step 4:
372 can be fit into 1710 4 times, resulting in a remainder of 222.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 1488 from 1710 to get 222.
Grab the next digit (1) from the dividend, add it to 222, then carry on: 2221 / 372

Step 5:
2221 divided by 372 is 5 with a remainder of 361.
Write down 5 as next digit of the result. 
Result so far: 245.0
Subtracting 1860 from 2221 leaves us with 361.
Append the next digit (1) from the dividend to 361 and continue with: 3611 / 372

Moving on to step 6:
3611 divided by 372 is 9 with a remainder of 263.
Put 9 as the next digit of the answer. 
Result so far: 2459.0
Subtract 3348 from 3611 to get 263.
Append the next digit (3) from the dividend to 263 and continue with: 2633 / 372

Moving on to step 7:
The number 372 fits into 2633 7 times, leaving a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 24597.0
The remainder is 29 after subtracting 2604 from 2633.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 372

On to step 8:
When dividing 296 by 372, we get 0 with a remainder of 296.
Write down 0 as next digit of the result. 
Result so far: 245970.0
The remainder is 296 after subtracting 0 from 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 9:
If we divide 2960 by 372, we get 7 and a remainder of 356.
Write down 7 as next digit of the result. 
Result so far: 245970.7
The remainder is 356 after subtracting 2604 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 10:
The number 372 fits into 3560 9 times, leaving a remainder of 212.
Write down 9 as next digit of the result. 
Result so far: 245970.79
Deduct 3348 from 3560 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 11:
When dividing 2120 by 372, we get 5 with a remainder of 260.
Record the quotient 5 as the next digit in the result. 
Result so far: 245970.795
If we subtract 1860 from 2120, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 12:
When dividing 2600 by 372, we get 6 with a remainder of 368.
Record the quotient 6 as the next digit in the result. 
Result so far: 245970.7956
If we take 2232 away from 2600, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 13:
372 goes into 3680 9 times with a remainder of 332.
Put 9 as the next digit of the answer. 
Result so far: 245970.79569
If we subtract 3348 from 3680, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 14:
3320 divided by 372 is 8 with a remainder of 344.
Use 8 as the next digit of our solution. 
Result so far: 245970.795698
If we subtract 2976 from 3320, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 15:
The number 372 fits into 3440 9 times, leaving a remainder of 92.
The next digit of our result is 9. 
Result so far: 245970.7956989
If we take 3348 away from 3440, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 16:
If we divide 920 by 372, we get 2 and a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 245970.79569892
Subtract 744 from 920 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Our division results in 245970.79569892 with a remaining 1.76e-07.
