Let's divide 72139931 by 848
We want to figure out the number of times 72139931 can be divided by 848.

Let's proceed to step 1:
848 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 848

Going ahead to step 2:
72 divided by 848 is 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 848

Moving on to step 3:
721 divided by 848 is 0 with a remainder of 721.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 721 to get 721.
Include the next digit (3) from the dividend after 721, then repeat: 7213 / 848

Let's proceed to step 4:
848 goes into 7213 8 times with a remainder of 429.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 6784 from 7213 to get 429.
Bring next digit (9) of the dividend behind the 429 and repeat the process: 4299 / 848

Going ahead to step 5:
848 can be fit into 4299 5 times, resulting in a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Deduct 4240 from 4299 and we're left with 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 848

Moving on to step 6:
The number 848 fits into 599 0 times, leaving a remainder of 599.
The number 0 becomes the next digit in our result. 
Result so far: 850.0
Deduct 0 from 599 and we're left with 599.
Include the next digit (3) from the dividend after 599, then repeat: 5993 / 848

On to step 7:
848 goes into 5993 7 times with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 8507.0
If we take 5936 away from 5993, we end up with 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 848

Let's proceed to step 8:
848 can be fit into 571 0 times, resulting in a remainder of 571.
The next digit of our result is 0. 
Result so far: 85070.0
Subtract 0 from 571 to get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Let's proceed to step 9:
848 can be fit into 5710 6 times, resulting in a remainder of 622.
The next digit of our result is 6. 
Result so far: 85070.6
Subtracting 5088 from 5710 leaves us with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Going ahead to step 10:
When dividing 6220 by 848, we get 7 with a remainder of 284.
The next digit of our result is 7. 
Result so far: 85070.67
Subtract 5936 from 6220 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 11:
When dividing 2840 by 848, we get 3 with a remainder of 296.
Use 3 as the next digit of our solution. 
Result so far: 85070.673
Subtracting 2544 from 2840 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 12:
When dividing 2960 by 848, we get 3 with a remainder of 416.
The next digit of our result is 3. 
Result so far: 85070.6733
If we subtract 2544 from 2960, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The final outcome is 85070.6733, with a leftover of 0.00416.
