78983157 ÷ 215 
We want to divide 78983157 by 215.

Let's proceed to step 1:
215 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 215

Step 2:
78 divided by 215 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 215

Advancing to step 3:
789 divided by 215 is 3 with a remainder of 144.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 645 away from 789, we end up with 144.
Append the next digit (8) from the dividend to 144 and continue with: 1448 / 215

Going ahead to step 4:
1448 divided by 215 is 6 with a remainder of 158.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 1290 from 1448 to get 158.
Bring next digit (3) of the dividend behind the 158 and repeat the process: 1583 / 215

Moving on to step 5:
The number 215 fits into 1583 7 times, leaving a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 367.0
Subtract 1505 from 1583 to get 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 215

On to step 6:
215 goes into 781 3 times with a remainder of 136.
Use 3 as the next digit of our solution. 
Result so far: 3673.0
Subtracting 645 from 781 leaves us with 136.
Append the next digit (5) from the dividend to 136 and continue with: 1365 / 215

Going ahead to step 7:
215 can be fit into 1365 6 times, resulting in a remainder of 75.
Put 6 as the next digit of the answer. 
Result so far: 36736.0
The remainder is 75 after subtracting 1290 from 1365.
Fetch the next digit (7) from the dividend, attach it to 75 and continue: 757 / 215

Moving on to step 8:
757 divided by 215 is 3 with a remainder of 112.
Write down 3 as next digit of the result. 
Result so far: 367363.0
The remainder is 112 after subtracting 645 from 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 9:
215 goes into 1120 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 367363.5
If we take 1075 away from 1120, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
215 goes into 450 2 times with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 367363.52
Subtract 430 from 450 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
215 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 367363.52
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
When dividing 2000 by 215, we get 9 with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 367363.5209
The remainder is 65 after subtracting 1935 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 13:
215 goes into 650 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 367363.52093
Subtract 645 from 650 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
The number 215 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 367363.52093
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 15:
215 can be fit into 500 2 times, resulting in a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 367363.5209302
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 16:
215 can be fit into 700 3 times, resulting in a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 367363.52093023
The remainder is 55 after subtracting 645 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 367363.52093023 and a remainder of 5.5e-08.
