We look at the division of 88561291 by 371 
The aim is to understand the frequency of 371 in 88561291.

Going ahead to step 1:
The number 371 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 371

Let's proceed to step 2:
371 can be fit into 88 0 times, resulting in a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Bring next digit (5) of the dividend behind the 88 and repeat the process: 885 / 371

On to step 3:
371 can be fit into 885 2 times, resulting in a remainder of 143.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 742 from 885 leaves us with 143.
Bring next digit (6) of the dividend behind the 143 and repeat the process: 1436 / 371

On to step 4:
If we divide 1436 by 371, we get 3 and a remainder of 323.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 1113 away from 1436, we end up with 323.
Fetch the next digit (1) from the dividend, attach it to 323 and continue: 3231 / 371

Step 5:
When dividing 3231 by 371, we get 8 with a remainder of 263.
Use 8 as the next digit of our solution. 
Result so far: 238.0
If we subtract 2968 from 3231, we get 263.
Take the next digit (2) from the dividend and append it to 263, then repeat: 2632 / 371

On to step 6:
371 can be fit into 2632 7 times, resulting in a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 2387.0
If we take 2597 away from 2632, we end up with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 371

Going ahead to step 7:
371 goes into 359 0 times with a remainder of 359.
Record the quotient 0 as the next digit in the result. 
Result so far: 23870.0
If we take 0 away from 359, we end up with 359.
Bring next digit (1) of the dividend behind the 359 and repeat the process: 3591 / 371

Step 8:
371 can be fit into 3591 9 times, resulting in a remainder of 252.
Write down 9 as next digit of the result. 
Result so far: 238709.0
Subtracting 3339 from 3591 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 9:
When dividing 2520 by 371, we get 6 with a remainder of 294.
Record the quotient 6 as the next digit in the result. 
Result so far: 238709.6
Subtracting 2226 from 2520 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 10:
The number 371 fits into 2940 7 times, leaving a remainder of 343.
The next digit of our result is 7. 
Result so far: 238709.67
If we subtract 2597 from 2940, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 11:
371 goes into 3430 9 times with a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 238709.679
If we take 3339 away from 3430, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 12:
The number 371 fits into 910 2 times, leaving a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 238709.6792
If we subtract 742 from 910, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 13:
The number 371 fits into 1680 4 times, leaving a remainder of 196.
Put 4 as the next digit of the answer. 
Result so far: 238709.67924
If we take 1484 away from 1680, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 14:
1960 divided by 371 is 5 with a remainder of 105.
The next digit of our result is 5. 
Result so far: 238709.679245
Subtract 1855 from 1960 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 15:
If we divide 1050 by 371, we get 2 and a remainder of 308.
Use 2 as the next digit of our solution. 
Result so far: 238709.6792452
Subtract 742 from 1050 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 16:
The number 371 fits into 3080 8 times, leaving a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 238709.67924528
The remainder is 112 after subtracting 2968 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The quotient of the division is 238709.67924528, and the remainder is 1.12e-07.
