Let's divide 12757579 by 191
We want to figure out the number of times 12757579 can be divided by 191.

On to step 1:
When dividing 1 by 191, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 191

On to step 2:
When dividing 12 by 191, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 191

Moving on to step 3:
191 can be fit into 127 0 times, resulting in a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 127 leaves us with 127.
Take the next digit (5) from the dividend and append it to 127, then repeat: 1275 / 191

Going ahead to step 4:
191 goes into 1275 6 times with a remainder of 129.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 1146 away from 1275, we end up with 129.
Take the next digit (7) from the dividend and append it to 129, then repeat: 1297 / 191

Moving on to step 5:
If we divide 1297 by 191, we get 6 and a remainder of 151.
Put 6 as the next digit of the answer. 
Result so far: 66.0
If we subtract 1146 from 1297, we get 151.
Take the next digit (5) from the dividend and append it to 151, then repeat: 1515 / 191

Going ahead to step 6:
The number 191 fits into 1515 7 times, leaving a remainder of 178.
The next digit of our result is 7. 
Result so far: 667.0
The remainder is 178 after subtracting 1337 from 1515.
Grab the next digit (7) from the dividend, add it to 178, then carry on: 1787 / 191

Going ahead to step 7:
The number 191 fits into 1787 9 times, leaving a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 6679.0
If we take 1719 away from 1787, we end up with 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 191

Advancing to step 8:
191 can be fit into 689 3 times, resulting in a remainder of 116.
Put 3 as the next digit of the answer. 
Result so far: 66793.0
If we subtract 573 from 689, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 9:
1160 divided by 191 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 66793.6
If we subtract 1146 from 1160, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
191 goes into 140 0 times with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 66793.6
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
191 goes into 1400 7 times with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 66793.607
Subtracting 1337 from 1400 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 12:
If we divide 630 by 191, we get 3 and a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 66793.6073
Subtracting 573 from 630 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 13:
570 divided by 191 is 2 with a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 66793.60732
The remainder is 188 after subtracting 382 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 14:
191 can be fit into 1880 9 times, resulting in a remainder of 161.
The number 9 becomes the next digit in our result. 
Result so far: 66793.607329
The remainder is 161 after subtracting 1719 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 15:
191 can be fit into 1610 8 times, resulting in a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 66793.6073298
If we subtract 1528 from 1610, 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.

Moving on to step 16:
820 divided by 191 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 66793.60732984
If we take 764 away from 820, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 66793.60732984 with a remainder of 5.6e-08.
