We're dividing 12375019 by 91 
We're looking to find how many times 91 goes into 12375019.

Advancing to step 1:
1 divided by 91 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 91

Moving on to step 2:
The number 91 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 91

Advancing to step 3:
When dividing 123 by 91, we get 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 91 from 123, we get 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 91

Advancing to step 4:
91 can be fit into 327 3 times, resulting in a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 273 from 327 leaves us with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 91

Going ahead to step 5:
If we divide 545 by 91, we get 5 and a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we take 455 away from 545, we end up with 90.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 91

Going ahead to step 6:
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: 1359.0
Subtract 819 from 900 to get 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 91

Advancing to step 7:
91 goes into 811 8 times with a remainder of 83.
The number 8 becomes the next digit in our result. 
Result so far: 13598.0
Deduct 728 from 811 and we're left with 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 91

Advancing to step 8:
The number 91 fits into 839 9 times, leaving a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 135989.0
If we subtract 819 from 839, 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.

Step 9:
When dividing 200 by 91, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 135989.2
If we take 182 away from 200, we end up 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.

Moving on to step 10:
The number 91 fits into 180 1 times, leaving a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 135989.21
Subtracting 91 from 180 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 11:
91 can be fit into 890 9 times, resulting in a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 135989.219
If we take 819 away from 890, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 12:
710 divided by 91 is 7 with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 135989.2197
Deduct 637 from 710 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 13:
730 divided by 91 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 135989.21978
If we take 728 away from 730, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
If we divide 20 by 91, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 135989.21978
If we take 0 away from 20, we end up with 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 15:
200 divided by 91 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 135989.2197802
Subtracting 182 from 200 leaves us 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 16:
If we divide 180 by 91, we get 1 and a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 135989.21978021
Subtracting 91 from 180 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

In conclusion, the division gives 135989.21978021 with a balance of 8.9e-08.
