Let's divide 91158091 by 769
We want to divide 91158091 by 769.

On to step 1:
If we divide 9 by 769, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 769

Going ahead to step 2:
If we divide 91 by 769, we get 0 and a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Bring next digit (1) of the dividend behind the 91 and repeat the process: 911 / 769

On to step 3:
When dividing 911 by 769, we get 1 with a remainder of 142.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 769 from 911 and we're left with 142.
Bring next digit (5) of the dividend behind the 142 and repeat the process: 1425 / 769

On to step 4:
When dividing 1425 by 769, we get 1 with a remainder of 656.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 769 from 1425 leaves us with 656.
Fetch the next digit (8) from the dividend, attach it to 656 and continue: 6568 / 769

On to step 5:
769 can be fit into 6568 8 times, resulting in a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 118.0
Subtracting 6152 from 6568 leaves us with 416.
Include the next digit (0) from the dividend after 416, then repeat: 4160 / 769

Let's proceed to step 6:
769 goes into 4160 5 times with a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 1185.0
Subtracting 3845 from 4160 leaves us with 315.
Fetch the next digit (9) from the dividend, attach it to 315 and continue: 3159 / 769

Step 7:
If we divide 3159 by 769, we get 4 and a remainder of 83.
Put 4 as the next digit of the answer. 
Result so far: 11854.0
If we take 3076 away from 3159, we end up with 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 769

Advancing to step 8:
The number 769 fits into 831 1 times, leaving a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 118541.0
Deduct 769 from 831 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
769 goes into 620 0 times with a remainder of 620.
Write down 0 as next digit of the result. 
Result so far: 118541.0
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 10:
When dividing 6200 by 769, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 118541.08
If we take 6152 away from 6200, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
769 can be fit into 480 0 times, resulting in a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 118541.08
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
If we divide 4800 by 769, we get 6 and a remainder of 186.
The number 6 becomes the next digit in our result. 
Result so far: 118541.0806
If we subtract 4614 from 4800, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 13:
When dividing 1860 by 769, we get 2 with a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 118541.08062
If we take 1538 away from 1860, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 14:
769 can be fit into 3220 4 times, resulting in a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 118541.080624
The remainder is 144 after subtracting 3076 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 15:
When dividing 1440 by 769, we get 1 with a remainder of 671.
The next digit of our result is 1. 
Result so far: 118541.0806241
The remainder is 671 after subtracting 769 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Let's proceed to step 16:
The number 769 fits into 6710 8 times, leaving a remainder of 558.
Put 8 as the next digit of the answer. 
Result so far: 118541.08062418
If we subtract 6152 from 6710, we get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

After the division, we end up with 118541.08062418 and a remainder of 5.58e-07.
