We look at the division of 15649771 by 91 
Let's see how many times 91 fits into 15649771.

Let's proceed to step 1:
91 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 91

Moving on to step 2:
When dividing 15 by 91, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 91

Step 3:
91 goes into 156 1 times with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 91 away from 156, we end up with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 91

Moving on to step 4:
If we divide 654 by 91, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 637 from 654 to get 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 91

Going ahead to step 5:
91 can be fit into 179 1 times, resulting in a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
Subtract 91 from 179 to get 88.
Grab the next digit (7) from the dividend, add it to 88, then carry on: 887 / 91

Step 6:
887 divided by 91 is 9 with a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 1719.0
Deduct 819 from 887 and we're left with 68.
Fetch the next digit (7) from the dividend, attach it to 68 and continue: 687 / 91

Moving on to step 7:
If we divide 687 by 91, we get 7 and a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 17197.0
Subtract 637 from 687 to get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 91

Advancing to step 8:
If we divide 501 by 91, we get 5 and a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 171975.0
Subtract 455 from 501 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
91 goes into 460 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 171975.5
Subtract 455 from 460 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
The number 91 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 171975.5
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
500 divided by 91 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 171975.505
Subtracting 455 from 500 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
450 divided by 91 is 4 with a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 171975.5054
If we subtract 364 from 450, 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.

Let's proceed to step 13:
The number 91 fits into 860 9 times, leaving a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 171975.50549
Subtract 819 from 860 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 14:
91 can be fit into 410 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 171975.505494
Deduct 364 from 410 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 15:
460 divided by 91 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 171975.5054945
The remainder is 5 after subtracting 455 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 16:
91 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 171975.5054945
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 171975.5054945 and a remainder of 5e-08.
