We divide 51663088 by 660
Our goal is to divide 51663088 by 660.

Step 1:
660 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 660

Going ahead to step 2:
660 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 660

Step 3:
660 can be fit into 516 0 times, resulting in a remainder of 516.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 516, we end up with 516.
Grab the next digit (6) from the dividend, add it to 516, then carry on: 5166 / 660

Moving on to step 4:
660 goes into 5166 7 times with a remainder of 546.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 4620 from 5166 and we're left with 546.
Include the next digit (3) from the dividend after 546, then repeat: 5463 / 660

Step 5:
660 can be fit into 5463 8 times, resulting in a remainder of 183.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 183 after subtracting 5280 from 5463.
Take the next digit (0) from the dividend and append it to 183, then repeat: 1830 / 660

Step 6:
The number 660 fits into 1830 2 times, leaving a remainder of 510.
Use 2 as the next digit of our solution. 
Result so far: 782.0
Deduct 1320 from 1830 and we're left with 510.
Grab the next digit (8) from the dividend, add it to 510, then carry on: 5108 / 660

Going ahead to step 7:
When dividing 5108 by 660, we get 7 with a remainder of 488.
Write down 7 as next digit of the result. 
Result so far: 7827.0
If we subtract 4620 from 5108, we get 488.
Append the next digit (8) from the dividend to 488 and continue with: 4888 / 660

Going ahead to step 8:
If we divide 4888 by 660, we get 7 and a remainder of 268.
Write down 7 as next digit of the result. 
Result so far: 78277.0
If we subtract 4620 from 4888, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 9:
If we divide 2680 by 660, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 78277.4
The remainder is 40 after subtracting 2640 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
When dividing 400 by 660, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 78277.4
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 11:
When dividing 4000 by 660, we get 6 with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 78277.406
If we subtract 3960 from 4000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
400 divided by 660 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 78277.406
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
When dividing 4000 by 660, we get 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 78277.40606
Deduct 3960 from 4000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
400 divided by 660 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 78277.40606
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 15:
When dividing 4000 by 660, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 78277.4060606
Subtracting 3960 from 4000 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
If we divide 400 by 660, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 78277.4060606
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 78277.4060606, with a leftover of 4e-07.
