Let's divide 663187 by 91
We want to divide 663187 by 91.

Advancing to step 1:
When dividing 6 by 91, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 91

Going ahead to step 2:
91 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 91

Step 3:
663 divided by 91 is 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 637 from 663, we get 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 91

Moving on to step 4:
91 can be fit into 261 2 times, resulting in a remainder of 79.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 79 after subtracting 182 from 261.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 91

On to step 5:
91 can be fit into 798 8 times, resulting in a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 728.0
Subtract 728 from 798 to get 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 91

Let's proceed to step 6:
The number 91 fits into 707 7 times, leaving a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 7287.0
Subtracting 637 from 707 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 7:
91 can be fit into 700 7 times, resulting in a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 7287.7
If we subtract 637 from 700, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 8:
The number 91 fits into 630 6 times, leaving a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 7287.76
Deduct 546 from 630 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 9:
840 divided by 91 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 7287.769
The remainder is 21 after subtracting 819 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 10:
91 can be fit into 210 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 7287.7692
Subtracting 182 from 210 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
91 goes into 280 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 7287.76923
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
91 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 7287.76923
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
91 goes into 700 7 times with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 7287.7692307
Deduct 637 from 700 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 14:
630 divided by 91 is 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 7287.76923076
If we take 546 away from 630, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The quotient of the division is 7287.76923076, and the remainder is 8.4e-08.
