83723787 divided by 978 
We want to figure out the number of times 83723787 can be divided by 978.

Going ahead to step 1:
When dividing 8 by 978, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 978

Step 2:
978 goes into 83 0 times with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 978

On to step 3:
When dividing 837 by 978, we get 0 with a remainder of 837.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 837, we get 837.
Grab the next digit (2) from the dividend, add it to 837, then carry on: 8372 / 978

Moving on to step 4:
When dividing 8372 by 978, we get 8 with a remainder of 548.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 7824 from 8372, we get 548.
Include the next digit (3) from the dividend after 548, then repeat: 5483 / 978

Moving on to step 5:
If we divide 5483 by 978, we get 5 and a remainder of 593.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 593 after subtracting 4890 from 5483.
Take the next digit (7) from the dividend and append it to 593, then repeat: 5937 / 978

Moving on to step 6:
The number 978 fits into 5937 6 times, leaving a remainder of 69.
Write down 6 as next digit of the result. 
Result so far: 856.0
The remainder is 69 after subtracting 5868 from 5937.
Fetch the next digit (8) from the dividend, attach it to 69 and continue: 698 / 978

Advancing to step 7:
The number 978 fits into 698 0 times, leaving a remainder of 698.
The number 0 becomes the next digit in our result. 
Result so far: 8560.0
If we take 0 away from 698, we end up with 698.
Take the next digit (7) from the dividend and append it to 698, then repeat: 6987 / 978

Moving on to step 8:
If we divide 6987 by 978, we get 7 and a remainder of 141.
Write down 7 as next digit of the result. 
Result so far: 85607.0
Subtracting 6846 from 6987 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 9:
The number 978 fits into 1410 1 times, leaving a remainder of 432.
The next digit of our result is 1. 
Result so far: 85607.1
If we take 978 away from 1410, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 10:
978 can be fit into 4320 4 times, resulting in a remainder of 408.
The number 4 becomes the next digit in our result. 
Result so far: 85607.14
Subtract 3912 from 4320 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 11:
4080 divided by 978 is 4 with a remainder of 168.
The next digit of our result is 4. 
Result so far: 85607.144
The remainder is 168 after subtracting 3912 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

After the division, we end up with 85607.144 and a remainder of 0.0168.
