We look at the division of 68160551 by 939 
We're looking to find how many times 939 goes into 68160551.

Going ahead to step 1:
The number 939 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 939

Let's proceed to step 2:
When dividing 68 by 939, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 939

Advancing to step 3:
939 can be fit into 681 0 times, resulting in a remainder of 681.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 681, we end up with 681.
Bring next digit (6) of the dividend behind the 681 and repeat the process: 6816 / 939

On to step 4:
When dividing 6816 by 939, we get 7 with a remainder of 243.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 243 after subtracting 6573 from 6816.
Include the next digit (0) from the dividend after 243, then repeat: 2430 / 939

Moving on to step 5:
When dividing 2430 by 939, we get 2 with a remainder of 552.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Deduct 1878 from 2430 and we're left with 552.
Include the next digit (5) from the dividend after 552, then repeat: 5525 / 939

Step 6:
When dividing 5525 by 939, we get 5 with a remainder of 830.
The number 5 becomes the next digit in our result. 
Result so far: 725.0
The remainder is 830 after subtracting 4695 from 5525.
Bring next digit (5) of the dividend behind the 830 and repeat the process: 8305 / 939

Going ahead to step 7:
When dividing 8305 by 939, we get 8 with a remainder of 793.
Put 8 as the next digit of the answer. 
Result so far: 7258.0
The remainder is 793 after subtracting 7512 from 8305.
Include the next digit (1) from the dividend after 793, then repeat: 7931 / 939

Let's proceed to step 8:
The number 939 fits into 7931 8 times, leaving a remainder of 419.
Record the quotient 8 as the next digit in the result. 
Result so far: 72588.0
The remainder is 419 after subtracting 7512 from 7931.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 9:
The number 939 fits into 4190 4 times, leaving a remainder of 434.
The number 4 becomes the next digit in our result. 
Result so far: 72588.4
If we subtract 3756 from 4190, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 10:
939 goes into 4340 4 times with a remainder of 584.
The next digit of our result is 4. 
Result so far: 72588.44
The remainder is 584 after subtracting 3756 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

After the division, we end up with 72588.44 and a remainder of 0.584.
