We're dividing 91171029 by 29 
Let's see how many times 29 fits into 91171029.

On to step 1:
The number 29 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 29

Moving on to step 2:
If we divide 91 by 29, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 87 from 91 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 29

Let's proceed to step 3:
If we divide 41 by 29, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 29 from 41, we get 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 29

Let's proceed to step 4:
29 can be fit into 127 4 times, resulting in a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 314.0
If we take 116 away from 127, we end up with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 29

On to step 5:
29 goes into 111 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 3143.0
The remainder is 24 after subtracting 87 from 111.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 29

Advancing to step 6:
If we divide 240 by 29, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 31438.0
Subtract 232 from 240 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 29

Step 7:
The number 29 fits into 82 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 314382.0
If we subtract 58 from 82, we get 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 29

Moving on to step 8:
249 divided by 29 is 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 3143828.0
If we take 232 away from 249, 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.

On to step 9:
170 divided by 29 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 3143828.5
Subtract 145 from 170 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
If we divide 250 by 29, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 3143828.58
Deduct 232 from 250 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
29 can be fit into 180 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 3143828.586
Subtract 174 from 180 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
29 can be fit into 60 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 3143828.5862
Subtract 58 from 60 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
29 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3143828.5862
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
When dividing 200 by 29, we get 6 with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 3143828.586206
If we subtract 174 from 200, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 15:
When dividing 260 by 29, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 3143828.5862068
Deduct 232 from 260 and we're left 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.

On to step 16:
The number 29 fits into 280 9 times, leaving a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 3143828.58620689
The remainder is 19 after subtracting 261 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 3143828.58620689, with a leftover of 1.9e-08.
