We look at the division of 91017439 by 653 
Our goal is to divide 91017439 by 653.

Going ahead to step 1:
653 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 653

Going ahead to step 2:
The number 653 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 653

Step 3:
If we divide 910 by 653, we get 1 and a remainder of 257.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 653 from 910 and we're left with 257.
Bring next digit (1) of the dividend behind the 257 and repeat the process: 2571 / 653

Step 4:
653 goes into 2571 3 times with a remainder of 612.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1959 from 2571 leaves us with 612.
Bring next digit (7) of the dividend behind the 612 and repeat the process: 6127 / 653

Advancing to step 5:
The number 653 fits into 6127 9 times, leaving a remainder of 250.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
The remainder is 250 after subtracting 5877 from 6127.
Include the next digit (4) from the dividend after 250, then repeat: 2504 / 653

Advancing to step 6:
When dividing 2504 by 653, we get 3 with a remainder of 545.
The number 3 becomes the next digit in our result. 
Result so far: 1393.0
The remainder is 545 after subtracting 1959 from 2504.
Include the next digit (3) from the dividend after 545, then repeat: 5453 / 653

Step 7:
5453 divided by 653 is 8 with a remainder of 229.
Put 8 as the next digit of the answer. 
Result so far: 13938.0
The remainder is 229 after subtracting 5224 from 5453.
Bring next digit (9) of the dividend behind the 229 and repeat the process: 2299 / 653

On to step 8:
653 can be fit into 2299 3 times, resulting in a remainder of 340.
Put 3 as the next digit of the answer. 
Result so far: 139383.0
Subtracting 1959 from 2299 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 9:
653 can be fit into 3400 5 times, resulting in a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 139383.5
Deduct 3265 from 3400 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 10:
653 can be fit into 1350 2 times, resulting in a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 139383.52
Subtracting 1306 from 1350 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
440 divided by 653 is 0 with a remainder of 440.
The next digit of our result is 0. 
Result so far: 139383.52
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 12:
If we divide 4400 by 653, we get 6 and a remainder of 482.
Use 6 as the next digit of our solution. 
Result so far: 139383.5206
Subtract 3918 from 4400 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 13:
When dividing 4820 by 653, we get 7 with a remainder of 249.
Put 7 as the next digit of the answer. 
Result so far: 139383.52067
If we subtract 4571 from 4820, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 14:
If we divide 2490 by 653, we get 3 and a remainder of 531.
Use 3 as the next digit of our solution. 
Result so far: 139383.520673
If we subtract 1959 from 2490, we get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 15:
653 goes into 5310 8 times with a remainder of 86.
The next digit of our result is 8. 
Result so far: 139383.5206738
If we subtract 5224 from 5310, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 16:
The number 653 fits into 860 1 times, leaving a remainder of 207.
The number 1 becomes the next digit in our result. 
Result so far: 139383.52067381
Deduct 653 from 860 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

After the division, we end up with 139383.52067381 and a remainder of 2.07e-07.
