23699959 divided by 978 
We want to divide 23699959 by 978.

Going ahead to step 1:
978 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 978

Moving on to step 2:
If we divide 23 by 978, we get 0 and a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 978

On to step 3:
978 goes into 236 0 times with a remainder of 236.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 236, we end up with 236.
Bring next digit (9) of the dividend behind the 236 and repeat the process: 2369 / 978

On to step 4:
978 can be fit into 2369 2 times, resulting in a remainder of 413.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1956 from 2369 leaves us with 413.
Take the next digit (9) from the dividend and append it to 413, then repeat: 4139 / 978

Step 5:
The number 978 fits into 4139 4 times, leaving a remainder of 227.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 3912 away from 4139, we end up with 227.
Bring next digit (9) of the dividend behind the 227 and repeat the process: 2279 / 978

Step 6:
If we divide 2279 by 978, we get 2 and a remainder of 323.
Put 2 as the next digit of the answer. 
Result so far: 242.0
Deduct 1956 from 2279 and we're left with 323.
Take the next digit (5) from the dividend and append it to 323, then repeat: 3235 / 978

Going ahead to step 7:
978 can be fit into 3235 3 times, resulting in a remainder of 301.
Use 3 as the next digit of our solution. 
Result so far: 2423.0
If we take 2934 away from 3235, we end up with 301.
Grab the next digit (9) from the dividend, add it to 301, then carry on: 3019 / 978

Moving on to step 8:
978 goes into 3019 3 times with a remainder of 85.
Put 3 as the next digit of the answer. 
Result so far: 24233.0
If we take 2934 away from 3019, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
When dividing 850 by 978, we get 0 with a remainder of 850.
Put 0 as the next digit of the answer. 
Result so far: 24233.0
Subtract 0 from 850 to get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Let's proceed to step 10:
8500 divided by 978 is 8 with a remainder of 676.
Use 8 as the next digit of our solution. 
Result so far: 24233.08
If we take 7824 away from 8500, we end up with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Advancing to step 11:
When dividing 6760 by 978, we get 6 with a remainder of 892.
Put 6 as the next digit of the answer. 
Result so far: 24233.086
Deduct 5868 from 6760 and we're left with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Let's proceed to step 12:
978 goes into 8920 9 times with a remainder of 118.
Use 9 as the next digit of our solution. 
Result so far: 24233.0869
Subtracting 8802 from 8920 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 13:
The number 978 fits into 1180 1 times, leaving a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 24233.08691
Deduct 978 from 1180 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 14:
When dividing 2020 by 978, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 24233.086912
If we take 1956 away from 2020, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
If we divide 640 by 978, we get 0 and a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 24233.086912
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 16:
978 goes into 6400 6 times with a remainder of 532.
Use 6 as the next digit of our solution. 
Result so far: 24233.08691206
Subtracting 5868 from 6400 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

The final outcome is 24233.08691206, with a leftover of 5.32e-07.
