838309 ÷ 91 
We want to figure out the number of times 838309 can be divided by 91.

Going ahead to step 1:
8 divided by 91 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 91

Going ahead to step 2:
If we divide 83 by 91, we get 0 and a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Bring next digit (8) of the dividend behind the 83 and repeat the process: 838 / 91

Going ahead to step 3:
The number 91 fits into 838 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 819 from 838 leaves us with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 91

Moving on to step 4:
91 can be fit into 193 2 times, resulting in a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 92.0
The remainder is 11 after subtracting 182 from 193.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 91

On to step 5:
The number 91 fits into 110 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 921.0
If we take 91 away from 110, we end up with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 91

On to step 6:
199 divided by 91 is 2 with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 9212.0
If we take 182 away from 199, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
91 goes into 170 1 times with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 9212.1
Subtracting 91 from 170 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 8:
91 can be fit into 790 8 times, resulting in a remainder of 62.
The next digit of our result is 8. 
Result so far: 9212.18
Deduct 728 from 790 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:
91 goes into 620 6 times with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 9212.186
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
740 divided by 91 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 9212.1868
If we subtract 728 from 740, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
When dividing 120 by 91, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 9212.18681
If we subtract 91 from 120, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
290 divided by 91 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 9212.186813
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
91 goes into 170 1 times with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 9212.1868131
Subtracting 91 from 170 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 14:
790 divided by 91 is 8 with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 9212.18681318
The remainder is 62 after subtracting 728 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 9212.18681318, and the remainder is 6.2e-08.
