Let's divide 215707 by 88
The aim is to understand the frequency of 88 in 215707.

Advancing to step 1:
88 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 88

Advancing to step 2:
21 divided by 88 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 88

Let's proceed to step 3:
88 goes into 215 2 times with a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 176 from 215 to get 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 88

Going ahead to step 4:
If we divide 397 by 88, we get 4 and a remainder of 45.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 352 away from 397, we end up with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 88

Moving on to step 5:
88 goes into 450 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 245.0
Subtract 440 from 450 to get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 88

Advancing to step 6:
107 divided by 88 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 2451.0
Subtracting 88 from 107 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
When dividing 190 by 88, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2451.2
Subtracting 176 from 190 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
88 can be fit into 140 1 times, resulting in a remainder of 52.
The next digit of our result is 1. 
Result so far: 2451.21
Subtracting 88 from 140 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
88 can be fit into 520 5 times, resulting in a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 2451.215
If we take 440 away from 520, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
When dividing 800 by 88, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 2451.2159
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
80 divided by 88 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 2451.2159
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
The number 88 fits into 800 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 2451.215909
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
The number 88 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 2451.215909
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
When dividing 800 by 88, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 2451.21590909
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 2451.21590909, with a leftover of 8e-09.
