99511237 ÷ 978 
We want to figure out the number of times 99511237 can be divided by 978.

Advancing to step 1:
978 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 978

Moving on to step 2:
978 goes into 99 0 times with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Append the next digit (5) from the dividend to 99 and continue with: 995 / 978

On to step 3:
If we divide 995 by 978, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 17 after subtracting 978 from 995.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 978

Going ahead to step 4:
The number 978 fits into 171 0 times, leaving a remainder of 171.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 171, we get 171.
Append the next digit (1) from the dividend to 171 and continue with: 1711 / 978

Advancing to step 5:
978 goes into 1711 1 times with a remainder of 733.
The next digit of our result is 1. 
Result so far: 101.0
Subtracting 978 from 1711 leaves us with 733.
Include the next digit (2) from the dividend after 733, then repeat: 7332 / 978

On to step 6:
7332 divided by 978 is 7 with a remainder of 486.
The next digit of our result is 7. 
Result so far: 1017.0
If we subtract 6846 from 7332, we get 486.
Bring next digit (3) of the dividend behind the 486 and repeat the process: 4863 / 978

On to step 7:
978 goes into 4863 4 times with a remainder of 951.
The number 4 becomes the next digit in our result. 
Result so far: 10174.0
Deduct 3912 from 4863 and we're left with 951.
Grab the next digit (7) from the dividend, add it to 951, then carry on: 9517 / 978

Moving on to step 8:
If we divide 9517 by 978, we get 9 and a remainder of 715.
The next digit of our result is 9. 
Result so far: 101749.0
If we subtract 8802 from 9517, we get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Advancing to step 9:
When dividing 7150 by 978, we get 7 with a remainder of 304.
Use 7 as the next digit of our solution. 
Result so far: 101749.7
If we take 6846 away from 7150, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 10:
The number 978 fits into 3040 3 times, leaving a remainder of 106.
Put 3 as the next digit of the answer. 
Result so far: 101749.73
Subtract 2934 from 3040 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 11:
978 goes into 1060 1 times with a remainder of 82.
The next digit of our result is 1. 
Result so far: 101749.731
The remainder is 82 after subtracting 978 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 12:
820 divided by 978 is 0 with a remainder of 820.
The next digit of our result is 0. 
Result so far: 101749.731
If we subtract 0 from 820, we get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 13:
8200 divided by 978 is 8 with a remainder of 376.
Write down 8 as next digit of the result. 
Result so far: 101749.73108
Subtracting 7824 from 8200 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 14:
3760 divided by 978 is 3 with a remainder of 826.
Record the quotient 3 as the next digit in the result. 
Result so far: 101749.731083
Subtract 2934 from 3760 to get 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Going ahead to step 15:
The number 978 fits into 8260 8 times, leaving a remainder of 436.
Use 8 as the next digit of our solution. 
Result so far: 101749.7310838
Subtract 7824 from 8260 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 16:
978 goes into 4360 4 times with a remainder of 448.
Put 4 as the next digit of the answer. 
Result so far: 101749.73108384
If we subtract 3912 from 4360, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final outcome is 101749.73108384, with a leftover of 4.48e-07.
