220631 ÷ 78 
We want to divide 220631 by 78.

Going ahead to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 78

Step 2:
22 divided by 78 is 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 78

Going ahead to step 3:
78 goes into 220 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 156 from 220 leaves us with 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 78

On to step 4:
When dividing 646 by 78, we get 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 22 after subtracting 624 from 646.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 78

On to step 5:
The number 78 fits into 223 2 times, leaving a remainder of 67.
Use 2 as the next digit of our solution. 
Result so far: 282.0
If we take 156 away from 223, we end up with 67.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 78

Advancing to step 6:
If we divide 671 by 78, we get 8 and a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 2828.0
Subtracting 624 from 671 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
When dividing 470 by 78, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 2828.6
If we subtract 468 from 470, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2828.6
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 78 is 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 2828.602
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
The number 78 fits into 440 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2828.6025
Subtracting 390 from 440 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
If we divide 500 by 78, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 2828.60256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
78 goes into 320 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2828.602564
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
78 goes into 80 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 2828.6025641
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
20 divided by 78 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 2828.6025641
Subtract 0 from 20 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.

The final outcome is 2828.6025641, with a leftover of 2e-08.
