638545 divided by 88 
The aim is to understand the frequency of 88 in 638545.

Let's proceed to step 1:
The number 88 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 88

Step 2:
The number 88 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 88

Step 3:
88 goes into 638 7 times with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 616 from 638 to get 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 88

On to step 4:
88 goes into 225 2 times with a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 72.0
Subtract 176 from 225 to get 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 88

Advancing to step 5:
88 goes into 494 5 times with a remainder of 54.
Use 5 as the next digit of our solution. 
Result so far: 725.0
The remainder is 54 after subtracting 440 from 494.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 88

On to step 6:
If we divide 545 by 88, we get 6 and a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 7256.0
Deduct 528 from 545 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
The number 88 fits into 170 1 times, leaving a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 7256.1
If we take 88 away from 170, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 8:
When dividing 820 by 88, we get 9 with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 7256.19
Subtract 792 from 820 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
When dividing 280 by 88, we get 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 7256.193
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 88, we get 1 and a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 7256.1931
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.

Advancing to step 11:
88 goes into 720 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 7256.19318
If we take 704 away from 720, we end up 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.

Step 12:
If we divide 160 by 88, we get 1 and a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 7256.193181
If we subtract 88 from 160, we 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 13:
720 divided by 88 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 7256.1931818
If we take 704 away from 720, we end up 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.

Moving on to step 14:
If we divide 160 by 88, we get 1 and a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 7256.19318181
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.

After the division, we end up with 7256.19318181 and a remainder of 7.2e-08.
