We're dividing 91525321 by 561 
Let's see how many times 561 fits into 91525321.

Advancing to step 1:
9 divided by 561 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 561

Step 2:
91 divided by 561 is 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (5) from the dividend and append it to 91, then repeat: 915 / 561

Advancing to step 3:
If we divide 915 by 561, we get 1 and a remainder of 354.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 561 from 915 and we're left with 354.
Grab the next digit (2) from the dividend, add it to 354, then carry on: 3542 / 561

Step 4:
If we divide 3542 by 561, we get 6 and a remainder of 176.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 176 after subtracting 3366 from 3542.
Include the next digit (5) from the dividend after 176, then repeat: 1765 / 561

Advancing to step 5:
If we divide 1765 by 561, we get 3 and a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 163.0
The remainder is 82 after subtracting 1683 from 1765.
Fetch the next digit (3) from the dividend, attach it to 82 and continue: 823 / 561

On to step 6:
The number 561 fits into 823 1 times, leaving a remainder of 262.
Use 1 as the next digit of our solution. 
Result so far: 1631.0
Deduct 561 from 823 and we're left with 262.
Include the next digit (2) from the dividend after 262, then repeat: 2622 / 561

On to step 7:
561 can be fit into 2622 4 times, resulting in a remainder of 378.
Use 4 as the next digit of our solution. 
Result so far: 16314.0
If we subtract 2244 from 2622, we get 378.
Take the next digit (1) from the dividend and append it to 378, then repeat: 3781 / 561

Step 8:
When dividing 3781 by 561, we get 6 with a remainder of 415.
Use 6 as the next digit of our solution. 
Result so far: 163146.0
Subtract 3366 from 3781 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 9:
If we divide 4150 by 561, we get 7 and a remainder of 223.
The next digit of our result is 7. 
Result so far: 163146.7
Deduct 3927 from 4150 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 10:
If we divide 2230 by 561, we get 3 and a remainder of 547.
Write down 3 as next digit of the result. 
Result so far: 163146.73
If we take 1683 away from 2230, we end up with 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Going ahead to step 11:
561 can be fit into 5470 9 times, resulting in a remainder of 421.
The number 9 becomes the next digit in our result. 
Result so far: 163146.739
Deduct 5049 from 5470 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Moving on to step 12:
4210 divided by 561 is 7 with a remainder of 283.
The number 7 becomes the next digit in our result. 
Result so far: 163146.7397
Subtracting 3927 from 4210 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 13:
The number 561 fits into 2830 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 163146.73975
If we take 2805 away from 2830, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
If we divide 250 by 561, we get 0 and a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 163146.73975
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 15:
When dividing 2500 by 561, we get 4 with a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 163146.7397504
The remainder is 256 after subtracting 2244 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 16:
561 can be fit into 2560 4 times, resulting in a remainder of 316.
Use 4 as the next digit of our solution. 
Result so far: 163146.73975044
Subtract 2244 from 2560 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

In conclusion, the division gives 163146.73975044 with a balance of 3.16e-07.
