89101371 ÷ 561 
Our goal is to divide 89101371 by 561.

Let's proceed to step 1:
When dividing 8 by 561, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 561

Step 2:
When dividing 89 by 561, we get 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 561

Let's proceed to step 3:
561 can be fit into 891 1 times, resulting in a remainder of 330.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 561 from 891 to get 330.
Bring next digit (0) of the dividend behind the 330 and repeat the process: 3300 / 561

On to step 4:
561 goes into 3300 5 times with a remainder of 495.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2805 from 3300 and we're left with 495.
Grab the next digit (1) from the dividend, add it to 495, then carry on: 4951 / 561

Going ahead to step 5:
When dividing 4951 by 561, we get 8 with a remainder of 463.
The next digit of our result is 8. 
Result so far: 158.0
If we subtract 4488 from 4951, we get 463.
Fetch the next digit (3) from the dividend, attach it to 463 and continue: 4633 / 561

Advancing to step 6:
561 goes into 4633 8 times with a remainder of 145.
Record the quotient 8 as the next digit in the result. 
Result so far: 1588.0
Deduct 4488 from 4633 and we're left with 145.
Append the next digit (7) from the dividend to 145 and continue with: 1457 / 561

Advancing to step 7:
When dividing 1457 by 561, we get 2 with a remainder of 335.
Put 2 as the next digit of the answer. 
Result so far: 15882.0
If we subtract 1122 from 1457, we get 335.
Append the next digit (1) from the dividend to 335 and continue with: 3351 / 561

Going ahead to step 8:
561 can be fit into 3351 5 times, resulting in a remainder of 546.
Record the quotient 5 as the next digit in the result. 
Result so far: 158825.0
Subtract 2805 from 3351 to get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 9:
The number 561 fits into 5460 9 times, leaving a remainder of 411.
Record the quotient 9 as the next digit in the result. 
Result so far: 158825.9
If we take 5049 away from 5460, we end up with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 10:
561 goes into 4110 7 times with a remainder of 183.
Write down 7 as next digit of the result. 
Result so far: 158825.97
If we take 3927 away from 4110, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 11:
If we divide 1830 by 561, we get 3 and a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 158825.973
If we subtract 1683 from 1830, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 12:
561 can be fit into 1470 2 times, resulting in a remainder of 348.
The number 2 becomes the next digit in our result. 
Result so far: 158825.9732
If we take 1122 away from 1470, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 13:
561 goes into 3480 6 times with a remainder of 114.
The number 6 becomes the next digit in our result. 
Result so far: 158825.97326
Subtracting 3366 from 3480 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 14:
If we divide 1140 by 561, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 158825.973262
Deduct 1122 from 1140 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 15:
561 can be fit into 180 0 times, resulting in a remainder of 180.
The next digit of our result is 0. 
Result so far: 158825.973262
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 16:
561 can be fit into 1800 3 times, resulting in a remainder of 117.
Use 3 as the next digit of our solution. 
Result so far: 158825.97326203
If we subtract 1683 from 1800, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Our division results in 158825.97326203 with a remaining 1.17e-07.
