We're dividing 88402697 by 563 
We want to divide 88402697 by 563.

Going ahead to step 1:
563 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
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 / 563

On to step 2:
When dividing 88 by 563, we get 0 with a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Append the next digit (4) from the dividend to 88 and continue with: 884 / 563

Advancing to step 3:
If we divide 884 by 563, we get 1 and a remainder of 321.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 563 from 884 and we're left with 321.
Append the next digit (0) from the dividend to 321 and continue with: 3210 / 563

Going ahead to step 4:
When dividing 3210 by 563, we get 5 with a remainder of 395.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 395 after subtracting 2815 from 3210.
Include the next digit (2) from the dividend after 395, then repeat: 3952 / 563

Advancing to step 5:
563 goes into 3952 7 times with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 157.0
If we subtract 3941 from 3952, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 563

Step 6:
116 divided by 563 is 0 with a remainder of 116.
Put 0 as the next digit of the answer. 
Result so far: 1570.0
The remainder is 116 after subtracting 0 from 116.
Fetch the next digit (9) from the dividend, attach it to 116 and continue: 1169 / 563

Let's proceed to step 7:
When dividing 1169 by 563, we get 2 with a remainder of 43.
The next digit of our result is 2. 
Result so far: 15702.0
If we take 1126 away from 1169, we end up with 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 563

On to step 8:
If we divide 437 by 563, we get 0 and a remainder of 437.
The next digit of our result is 0. 
Result so far: 157020.0
Subtract 0 from 437 to get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 9:
The number 563 fits into 4370 7 times, leaving a remainder of 429.
Use 7 as the next digit of our solution. 
Result so far: 157020.7
The remainder is 429 after subtracting 3941 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Let's proceed to step 10:
563 can be fit into 4290 7 times, resulting in a remainder of 349.
Record the quotient 7 as the next digit in the result. 
Result so far: 157020.77
Deduct 3941 from 4290 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

The final outcome is 157020.77, with a leftover of 0.349.
