We divide 400307 by 88
The aim is to understand the frequency of 88 in 400307.

On to step 1:
If we divide 4 by 88, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 88

Advancing to step 2:
88 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 88

Step 3:
400 divided by 88 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 352 from 400, we get 48.
Bring next digit (3) of the dividend behind the 48 and repeat the process: 483 / 88

Moving on to step 4:
The number 88 fits into 483 5 times, leaving a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we take 440 away from 483, we end up with 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 88

Moving on to step 5:
The number 88 fits into 430 4 times, leaving a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 454.0
Subtract 352 from 430 to get 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 88

Going ahead to step 6:
88 can be fit into 787 8 times, resulting in a remainder of 83.
Write down 8 as next digit of the result. 
Result so far: 4548.0
Subtracting 704 from 787 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 7:
The number 88 fits into 830 9 times, leaving a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 4548.9
Subtracting 792 from 830 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
380 divided by 88 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 4548.94
Deduct 352 from 380 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
The number 88 fits into 280 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 4548.943
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
88 can be fit into 160 1 times, resulting in a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 4548.9431
Subtract 88 from 160 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
720 divided by 88 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 4548.94318
Subtract 704 from 720 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
88 goes into 160 1 times with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 4548.943181
If we take 88 away from 160, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
The number 88 fits into 720 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 4548.9431818
Subtracting 704 from 720 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
If we divide 160 by 88, we get 1 and a remainder of 72.
The next digit of our result is 1. 
Result so far: 4548.94318181
Subtract 88 from 160 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 4548.94318181 and a remainder of 7.2e-08.
