We divide 51460294 by 660
We want to divide 51460294 by 660.

Advancing to step 1:
When dividing 5 by 660, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 660

Advancing to step 2:
660 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 660

Step 3:
660 can be fit into 514 0 times, resulting in a remainder of 514.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 514, we get 514.
Grab the next digit (6) from the dividend, add it to 514, then carry on: 5146 / 660

Going ahead to step 4:
The number 660 fits into 5146 7 times, leaving a remainder of 526.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 4620 from 5146 and we're left with 526.
Grab the next digit (0) from the dividend, add it to 526, then carry on: 5260 / 660

Advancing to step 5:
5260 divided by 660 is 7 with a remainder of 640.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtracting 4620 from 5260 leaves us with 640.
Take the next digit (2) from the dividend and append it to 640, then repeat: 6402 / 660

Moving on to step 6:
If we divide 6402 by 660, we get 9 and a remainder of 462.
The number 9 becomes the next digit in our result. 
Result so far: 779.0
If we subtract 5940 from 6402, we get 462.
Fetch the next digit (9) from the dividend, attach it to 462 and continue: 4629 / 660

Moving on to step 7:
4629 divided by 660 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 7797.0
Subtracting 4620 from 4629 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 660

Going ahead to step 8:
94 divided by 660 is 0 with a remainder of 94.
Record the quotient 0 as the next digit in the result. 
Result so far: 77970.0
If we take 0 away from 94, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 9:
940 divided by 660 is 1 with a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 77970.1
The remainder is 280 after subtracting 660 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 10:
When dividing 2800 by 660, we get 4 with a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 77970.14
If we take 2640 away from 2800, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
660 can be fit into 1600 2 times, resulting in a remainder of 280.
Put 2 as the next digit of the answer. 
Result so far: 77970.142
If we subtract 1320 from 1600, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
If we divide 2800 by 660, we get 4 and a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 77970.1424
Deduct 2640 from 2800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
660 goes into 1600 2 times with a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 77970.14242
The remainder is 280 after subtracting 1320 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 14:
The number 660 fits into 2800 4 times, leaving a remainder of 160.
The next digit of our result is 4. 
Result so far: 77970.142424
The remainder is 160 after subtracting 2640 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
1600 divided by 660 is 2 with a remainder of 280.
Put 2 as the next digit of the answer. 
Result so far: 77970.1424242
If we subtract 1320 from 1600, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 16:
The number 660 fits into 2800 4 times, leaving a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 77970.14242424
Subtract 2640 from 2800 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 77970.14242424, with a leftover of 1.6e-07.
