79281980 ÷ 678 
Our goal is to divide 79281980 by 678.

Advancing to step 1:
If we divide 7 by 678, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 678

Step 2:
The number 678 fits into 79 0 times, leaving a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 678

Let's proceed to step 3:
678 can be fit into 792 1 times, resulting in a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 678 from 792 to get 114.
Include the next digit (8) from the dividend after 114, then repeat: 1148 / 678

Let's proceed to step 4:
678 can be fit into 1148 1 times, resulting in a remainder of 470.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 678 from 1148 to get 470.
Append the next digit (1) from the dividend to 470 and continue with: 4701 / 678

On to step 5:
The number 678 fits into 4701 6 times, leaving a remainder of 633.
Put 6 as the next digit of the answer. 
Result so far: 116.0
If we take 4068 away from 4701, we end up with 633.
Take the next digit (9) from the dividend and append it to 633, then repeat: 6339 / 678

On to step 6:
6339 divided by 678 is 9 with a remainder of 237.
Use 9 as the next digit of our solution. 
Result so far: 1169.0
If we take 6102 away from 6339, we end up with 237.
Append the next digit (8) from the dividend to 237 and continue with: 2378 / 678

Advancing to step 7:
The number 678 fits into 2378 3 times, leaving a remainder of 344.
Record the quotient 3 as the next digit in the result. 
Result so far: 11693.0
If we subtract 2034 from 2378, we get 344.
Append the next digit (0) from the dividend to 344 and continue with: 3440 / 678

On to step 8:
If we divide 3440 by 678, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 116935.0
If we take 3390 away from 3440, we end up 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.

Advancing to step 9:
The number 678 fits into 500 0 times, leaving a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 116935.0
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 10:
678 goes into 5000 7 times with a remainder of 254.
Write down 7 as next digit of the result. 
Result so far: 116935.07
Deduct 4746 from 5000 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 11:
The number 678 fits into 2540 3 times, leaving a remainder of 506.
The number 3 becomes the next digit in our result. 
Result so far: 116935.073
The remainder is 506 after subtracting 2034 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Step 12:
When dividing 5060 by 678, we get 7 with a remainder of 314.
Write down 7 as next digit of the result. 
Result so far: 116935.0737
The remainder is 314 after subtracting 4746 from 5060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 13:
678 goes into 3140 4 times with a remainder of 428.
The number 4 becomes the next digit in our result. 
Result so far: 116935.07374
The remainder is 428 after subtracting 2712 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 14:
If we divide 4280 by 678, we get 6 and a remainder of 212.
Use 6 as the next digit of our solution. 
Result so far: 116935.073746
If we take 4068 away from 4280, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 15:
The number 678 fits into 2120 3 times, leaving a remainder of 86.
Put 3 as the next digit of the answer. 
Result so far: 116935.0737463
Deduct 2034 from 2120 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 16:
The number 678 fits into 860 1 times, leaving a remainder of 182.
Put 1 as the next digit of the answer. 
Result so far: 116935.07374631
Deduct 678 from 860 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The quotient of the division is 116935.07374631, and the remainder is 1.82e-07.
