636202 ÷ 91 
Our goal is to divide 636202 by 91.

Step 1:
When dividing 6 by 91, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 91

Let's proceed to step 2:
When dividing 63 by 91, we get 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 91

Moving on to step 3:
The number 91 fits into 636 6 times, leaving a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 546 from 636, we get 90.
Grab the next digit (2) from the dividend, add it to 90, then carry on: 902 / 91

Advancing to step 4:
91 goes into 902 9 times with a remainder of 83.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Deduct 819 from 902 and we're left with 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 91

On to step 5:
91 goes into 830 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 699.0
Subtracting 819 from 830 leaves us with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 91

Advancing to step 6:
91 goes into 112 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 6991.0
If we subtract 91 from 112, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
91 can be fit into 210 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 6991.2
If we take 182 away from 210, we end up 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.

Step 8:
91 can be fit into 280 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 6991.23
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
The number 91 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 6991.23
If we subtract 0 from 70, we get 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 10:
91 can be fit into 700 7 times, resulting in a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 6991.2307
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.

Step 11:
If we divide 630 by 91, we get 6 and a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 6991.23076
Subtract 546 from 630 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
91 can be fit into 840 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 6991.230769
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.

Advancing to step 13:
If we divide 210 by 91, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 6991.2307692
If we subtract 182 from 210, we get 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 14:
91 goes into 280 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 6991.23076923
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 6991.23076923, with a leftover of 7e-09.
