Let's divide 78940880 by 651
We want to divide 78940880 by 651.

Let's proceed to step 1:
When dividing 7 by 651, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 651

Step 2:
78 divided by 651 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.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 651

Advancing to step 3:
651 goes into 789 1 times with a remainder of 138.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 651 from 789, we get 138.
Include the next digit (4) from the dividend after 138, then repeat: 1384 / 651

On to step 4:
651 goes into 1384 2 times with a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1302 from 1384 leaves us with 82.
Take the next digit (0) from the dividend and append it to 82, then repeat: 820 / 651

Step 5:
820 divided by 651 is 1 with a remainder of 169.
Use 1 as the next digit of our solution. 
Result so far: 121.0
If we take 651 away from 820, we end up with 169.
Bring next digit (8) of the dividend behind the 169 and repeat the process: 1698 / 651

Let's proceed to step 6:
1698 divided by 651 is 2 with a remainder of 396.
Put 2 as the next digit of the answer. 
Result so far: 1212.0
The remainder is 396 after subtracting 1302 from 1698.
Bring next digit (8) of the dividend behind the 396 and repeat the process: 3968 / 651

Going ahead to step 7:
651 can be fit into 3968 6 times, resulting in a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 12126.0
If we take 3906 away from 3968, we end up with 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 651

On to step 8:
651 can be fit into 620 0 times, resulting in a remainder of 620.
Record the quotient 0 as the next digit in the result. 
Result so far: 121260.0
Subtract 0 from 620 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 9:
If we divide 6200 by 651, we get 9 and a remainder of 341.
Record the quotient 9 as the next digit in the result. 
Result so far: 121260.9
Deduct 5859 from 6200 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 10:
651 can be fit into 3410 5 times, resulting in a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 121260.95
The remainder is 155 after subtracting 3255 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 11:
When dividing 1550 by 651, we get 2 with a remainder of 248.
The next digit of our result is 2. 
Result so far: 121260.952
Subtract 1302 from 1550 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 12:
If we divide 2480 by 651, we get 3 and a remainder of 527.
Record the quotient 3 as the next digit in the result. 
Result so far: 121260.9523
If we subtract 1953 from 2480, we get 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

On to step 13:
5270 divided by 651 is 8 with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 121260.95238
If we subtract 5208 from 5270, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
651 can be fit into 620 0 times, resulting in a remainder of 620.
The number 0 becomes the next digit in our result. 
Result so far: 121260.95238
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 15:
The number 651 fits into 6200 9 times, leaving a remainder of 341.
Use 9 as the next digit of our solution. 
Result so far: 121260.9523809
If we take 5859 away from 6200, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 16:
651 can be fit into 3410 5 times, resulting in a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 121260.95238095
If we subtract 3255 from 3410, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The final outcome is 121260.95238095, with a leftover of 1.55e-07.
