We look at the division of 90838597 by 571 
We want to divide 90838597 by 571.

Going ahead to step 1:
The number 571 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 571

Let's proceed to step 2:
If we divide 90 by 571, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 571

Moving on to step 3:
If we divide 908 by 571, we get 1 and a remainder of 337.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 571 from 908 to get 337.
Append the next digit (3) from the dividend to 337 and continue with: 3373 / 571

Step 4:
571 can be fit into 3373 5 times, resulting in a remainder of 518.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2855 from 3373 and we're left with 518.
Append the next digit (8) from the dividend to 518 and continue with: 5188 / 571

Going ahead to step 5:
The number 571 fits into 5188 9 times, leaving a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Deduct 5139 from 5188 and we're left with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 571

Moving on to step 6:
The number 571 fits into 495 0 times, leaving a remainder of 495.
Put 0 as the next digit of the answer. 
Result so far: 1590.0
Subtracting 0 from 495 leaves us with 495.
Include the next digit (9) from the dividend after 495, then repeat: 4959 / 571

Advancing to step 7:
If we divide 4959 by 571, we get 8 and a remainder of 391.
Use 8 as the next digit of our solution. 
Result so far: 15908.0
Deduct 4568 from 4959 and we're left with 391.
Grab the next digit (7) from the dividend, add it to 391, then carry on: 3917 / 571

On to step 8:
When dividing 3917 by 571, we get 6 with a remainder of 491.
The next digit of our result is 6. 
Result so far: 159086.0
If we subtract 3426 from 3917, we get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Advancing to step 9:
571 goes into 4910 8 times with a remainder of 342.
Put 8 as the next digit of the answer. 
Result so far: 159086.8
Subtract 4568 from 4910 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 10:
571 goes into 3420 5 times with a remainder of 565.
The number 5 becomes the next digit in our result. 
Result so far: 159086.85
If we subtract 2855 from 3420, we get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Step 11:
The number 571 fits into 5650 9 times, leaving a remainder of 511.
Write down 9 as next digit of the result. 
Result so far: 159086.859
If we subtract 5139 from 5650, we get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

On to step 12:
571 can be fit into 5110 8 times, resulting in a remainder of 542.
The next digit of our result is 8. 
Result so far: 159086.8598
If we subtract 4568 from 5110, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Going ahead to step 13:
5420 divided by 571 is 9 with a remainder of 281.
Record the quotient 9 as the next digit in the result. 
Result so far: 159086.85989
If we take 5139 away from 5420, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 14:
571 goes into 2810 4 times with a remainder of 526.
The next digit of our result is 4. 
Result so far: 159086.859894
The remainder is 526 after subtracting 2284 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Moving on to step 15:
571 can be fit into 5260 9 times, resulting in a remainder of 121.
The next digit of our result is 9. 
Result so far: 159086.8598949
If we take 5139 away from 5260, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 16:
1210 divided by 571 is 2 with a remainder of 68.
The next digit of our result is 2. 
Result so far: 159086.85989492
Subtract 1142 from 1210 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 159086.85989492 with a balance of 6.8e-08.
