We look at the division of 5261868 by 660 
Let's see how many times 660 fits into 5261868.

Going ahead to step 1:
660 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 660

Let's proceed to step 2:
660 can be fit into 52 0 times, resulting in a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 660

Let's proceed to step 3:
The number 660 fits into 526 0 times, leaving a remainder of 526.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 526 to get 526.
Take the next digit (1) from the dividend and append it to 526, then repeat: 5261 / 660

Advancing to step 4:
5261 divided by 660 is 7 with a remainder of 641.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 4620 away from 5261, we end up with 641.
Grab the next digit (8) from the dividend, add it to 641, then carry on: 6418 / 660

Advancing to step 5:
660 can be fit into 6418 9 times, resulting in a remainder of 478.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtracting 5940 from 6418 leaves us with 478.
Fetch the next digit (6) from the dividend, attach it to 478 and continue: 4786 / 660

Advancing to step 6:
The number 660 fits into 4786 7 times, leaving a remainder of 166.
The number 7 becomes the next digit in our result. 
Result so far: 797.0
If we take 4620 away from 4786, we end up with 166.
Include the next digit (8) from the dividend after 166, then repeat: 1668 / 660

Let's proceed to step 7:
1668 divided by 660 is 2 with a remainder of 348.
The number 2 becomes the next digit in our result. 
Result so far: 7972.0
Subtracting 1320 from 1668 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 8:
3480 divided by 660 is 5 with a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 7972.5
If we take 3300 away from 3480, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
660 can be fit into 1800 2 times, resulting in a remainder of 480.
Write down 2 as next digit of the result. 
Result so far: 7972.52
Subtracting 1320 from 1800 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 10:
If we divide 4800 by 660, we get 7 and a remainder of 180.
Write down 7 as next digit of the result. 
Result so far: 7972.527
Subtracting 4620 from 4800 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
660 goes into 1800 2 times with a remainder of 480.
Write down 2 as next digit of the result. 
Result so far: 7972.5272
The remainder is 480 after subtracting 1320 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 12:
When dividing 4800 by 660, we get 7 with a remainder of 180.
The next digit of our result is 7. 
Result so far: 7972.52727
Subtract 4620 from 4800 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 13:
660 can be fit into 1800 2 times, resulting in a remainder of 480.
Put 2 as the next digit of the answer. 
Result so far: 7972.527272
Deduct 1320 from 1800 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 14:
660 goes into 4800 7 times with a remainder of 180.
Record the quotient 7 as the next digit in the result. 
Result so far: 7972.5272727
If we subtract 4620 from 4800, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 15:
1800 divided by 660 is 2 with a remainder of 480.
The next digit of our result is 2. 
Result so far: 7972.52727272
If we subtract 1320 from 1800, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Our division results in 7972.52727272 with a remaining 4.8e-07.
