We look at the division of 663801 by 88 
We're looking to find how many times 88 goes into 663801.

Step 1:
The number 88 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 88

Step 2:
If we divide 66 by 88, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 88

Step 3:
The number 88 fits into 663 7 times, leaving a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 616 from 663, we get 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 88

Moving on to step 4:
88 can be fit into 478 5 times, resulting in a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we take 440 away from 478, we end up with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 88

Advancing to step 5:
88 can be fit into 380 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 754.0
If we take 352 away from 380, we end up with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 88

Going ahead to step 6:
The number 88 fits into 281 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 7543.0
If we subtract 264 from 281, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
88 can be fit into 170 1 times, resulting in a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 7543.1
Subtracting 88 from 170 leaves us 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.

Step 8:
When dividing 820 by 88, we get 9 with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 7543.19
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:
88 goes into 280 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 7543.193
If we take 264 away from 280, 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.

Let's proceed to step 10:
If we divide 160 by 88, we get 1 and a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 7543.1931
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.

Step 11:
If we divide 720 by 88, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 7543.19318
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 12:
88 goes into 160 1 times with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 7543.193181
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:
If we divide 720 by 88, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7543.1931818
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.

Let's proceed to step 14:
88 goes into 160 1 times with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 7543.19318181
Deduct 88 from 160 and we're left 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.

In conclusion, the division gives 7543.19318181 with a balance of 7.2e-08.
