853407 ÷ 91 
Let's see how many times 91 fits into 853407.

Let's proceed to step 1:
If we divide 8 by 91, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 91

Let's proceed to step 2:
When dividing 85 by 91, we get 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Take the next digit (3) from the dividend and append it to 85, then repeat: 853 / 91

On to step 3:
91 goes into 853 9 times with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 819 from 853 leaves us with 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 91

Going ahead to step 4:
344 divided by 91 is 3 with a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtracting 273 from 344 leaves us with 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 91

On to step 5:
The number 91 fits into 710 7 times, leaving a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 937.0
If we subtract 637 from 710, we get 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 91

On to step 6:
If we divide 737 by 91, we get 8 and a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 9378.0
Subtracting 728 from 737 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 91 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 9378.0
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 8:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 9378.09
Deduct 819 from 900 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 9:
The number 91 fits into 810 8 times, leaving a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 9378.098
Deduct 728 from 810 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
91 goes into 820 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 9378.0989
Subtracting 819 from 820 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
91 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 9378.0989
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
The number 91 fits into 100 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 9378.098901
If we take 91 away from 100, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
91 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 9378.098901
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 14:
When dividing 900 by 91, we get 9 with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 9378.09890109
Subtract 819 from 900 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

After the division, we end up with 9378.09890109 and a remainder of 8.1e-08.
