89521697 ÷ 159 
Our goal is to divide 89521697 by 159.

Let's proceed to step 1:
159 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 159

Moving on to step 2:
159 can be fit into 89 0 times, resulting in a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Grab the next digit (5) from the dividend, add it to 89, then carry on: 895 / 159

Let's proceed to step 3:
When dividing 895 by 159, we get 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 795 from 895, we get 100.
Append the next digit (2) from the dividend to 100 and continue with: 1002 / 159

On to step 4:
1002 divided by 159 is 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 56.0
Subtract 954 from 1002 to get 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 159

Going ahead to step 5:
The number 159 fits into 481 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 563.0
Deduct 477 from 481 and we're left with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 159

On to step 6:
46 divided by 159 is 0 with a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 5630.0
Deduct 0 from 46 and we're left with 46.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 159

Going ahead to step 7:
159 goes into 469 2 times with a remainder of 151.
Write down 2 as next digit of the result. 
Result so far: 56302.0
Subtracting 318 from 469 leaves us with 151.
Fetch the next digit (7) from the dividend, attach it to 151 and continue: 1517 / 159

Moving on to step 8:
When dividing 1517 by 159, we get 9 with a remainder of 86.
Write down 9 as next digit of the result. 
Result so far: 563029.0
If we take 1431 away from 1517, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
159 goes into 860 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 563029.5
Subtract 795 from 860 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
159 goes into 650 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 563029.54
Deduct 636 from 650 and we're left 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.

On to step 11:
159 goes into 140 0 times with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 563029.54
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
If we divide 1400 by 159, we get 8 and a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 563029.5408
If we subtract 1272 from 1400, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 13:
If we divide 1280 by 159, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 563029.54088
If we take 1272 away from 1280, we end up 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 result is 563029.54088 with a remainder of 8e-06.
