516151 ÷ 91 
Our goal is to divide 516151 by 91.

On to step 1:
91 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 91

On to step 2:
91 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 91

Going ahead to step 3:
91 goes into 516 5 times with a remainder of 61.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 455 from 516 and we're left with 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 91

Going ahead to step 4:
The number 91 fits into 611 6 times, leaving a remainder of 65.
Put 6 as the next digit of the answer. 
Result so far: 56.0
If we subtract 546 from 611, we get 65.
Append the next digit (5) from the dividend to 65 and continue with: 655 / 91

Moving on to step 5:
655 divided by 91 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 567.0
The remainder is 18 after subtracting 637 from 655.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 91

On to step 6:
181 divided by 91 is 1 with a remainder of 90.
Use 1 as the next digit of our solution. 
Result so far: 5671.0
The remainder is 90 after subtracting 91 from 181.
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 7:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 5671.9
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.

Going ahead to step 8:
91 can be fit into 810 8 times, resulting in a remainder of 82.
The next digit of our result is 8. 
Result so far: 5671.98
If we subtract 728 from 810, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 9:
When dividing 820 by 91, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 5671.989
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.

Moving on to step 10:
If we divide 10 by 91, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5671.989
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
91 can be fit into 100 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 5671.98901
Subtracting 91 from 100 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 12:
91 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 5671.98901
Deduct 0 from 90 and we're left 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.

Advancing to step 13:
If we divide 900 by 91, we get 9 and a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 5671.9890109
Subtracting 819 from 900 leaves us 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.

Going ahead to step 14:
810 divided by 91 is 8 with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 5671.98901098
If we subtract 728 from 810, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 5671.98901098 with a remaining 8.2e-08.
