72157305 divided by 766 
We want to figure out the number of times 72157305 can be divided by 766.

Moving on to step 1:
766 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 766

Moving on to step 2:
766 can be fit into 72 0 times, resulting in a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 766

Advancing to step 3:
766 can be fit into 721 0 times, resulting in a remainder of 721.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 721 after subtracting 0 from 721.
Grab the next digit (5) from the dividend, add it to 721, then carry on: 7215 / 766

Advancing to step 4:
766 can be fit into 7215 9 times, resulting in a remainder of 321.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 321 after subtracting 6894 from 7215.
Grab the next digit (7) from the dividend, add it to 321, then carry on: 3217 / 766

On to step 5:
When dividing 3217 by 766, we get 4 with a remainder of 153.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Subtracting 3064 from 3217 leaves us with 153.
Bring next digit (3) of the dividend behind the 153 and repeat the process: 1533 / 766

Going ahead to step 6:
When dividing 1533 by 766, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 942.0
Subtracting 1532 from 1533 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 766

Moving on to step 7:
If we divide 10 by 766, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 9420.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 766

Moving on to step 8:
If we divide 105 by 766, we get 0 and a remainder of 105.
The next digit of our result is 0. 
Result so far: 94200.0
The remainder is 105 after subtracting 0 from 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 9:
If we divide 1050 by 766, we get 1 and a remainder of 284.
Put 1 as the next digit of the answer. 
Result so far: 94200.1
The remainder is 284 after subtracting 766 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 10:
The number 766 fits into 2840 3 times, leaving a remainder of 542.
Put 3 as the next digit of the answer. 
Result so far: 94200.13
The remainder is 542 after subtracting 2298 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 11:
5420 divided by 766 is 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 94200.137
The remainder is 58 after subtracting 5362 from 5420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
The number 766 fits into 580 0 times, leaving a remainder of 580.
Use 0 as the next digit of our solution. 
Result so far: 94200.137
If we take 0 away from 580, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 13:
766 goes into 5800 7 times with a remainder of 438.
Put 7 as the next digit of the answer. 
Result so far: 94200.13707
If we take 5362 away from 5800, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 14:
The number 766 fits into 4380 5 times, leaving a remainder of 550.
The next digit of our result is 5. 
Result so far: 94200.137075
If we subtract 3830 from 4380, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 15:
The number 766 fits into 5500 7 times, leaving a remainder of 138.
Put 7 as the next digit of the answer. 
Result so far: 94200.1370757
Subtract 5362 from 5500 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 16:
If we divide 1380 by 766, we get 1 and a remainder of 614.
Use 1 as the next digit of our solution. 
Result so far: 94200.13707571
Subtract 766 from 1380 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

The final outcome is 94200.13707571, with a leftover of 6.14e-07.
