We divide 39880100 by 651
We're looking to find how many times 651 goes into 39880100.

On to step 1:
651 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 651

On to step 2:
651 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 651

Let's proceed to step 3:
If we divide 398 by 651, we get 0 and a remainder of 398.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 398 after subtracting 0 from 398.
Include the next digit (8) from the dividend after 398, then repeat: 3988 / 651

Advancing to step 4:
The number 651 fits into 3988 6 times, leaving a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 3906 from 3988 leaves us with 82.
Fetch the next digit (0) from the dividend, attach it to 82 and continue: 820 / 651

Advancing to step 5:
651 can be fit into 820 1 times, resulting in a remainder of 169.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtract 651 from 820 to get 169.
Take the next digit (1) from the dividend and append it to 169, then repeat: 1691 / 651

On to step 6:
651 goes into 1691 2 times with a remainder of 389.
Record the quotient 2 as the next digit in the result. 
Result so far: 612.0
Deduct 1302 from 1691 and we're left with 389.
Grab the next digit (0) from the dividend, add it to 389, then carry on: 3890 / 651

Moving on to step 7:
The number 651 fits into 3890 5 times, leaving a remainder of 635.
Use 5 as the next digit of our solution. 
Result so far: 6125.0
If we subtract 3255 from 3890, we get 635.
Take the next digit (0) from the dividend and append it to 635, then repeat: 6350 / 651

Step 8:
The number 651 fits into 6350 9 times, leaving a remainder of 491.
Put 9 as the next digit of the answer. 
Result so far: 61259.0
Subtracting 5859 from 6350 leaves us with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Step 9:
The number 651 fits into 4910 7 times, leaving a remainder of 353.
Use 7 as the next digit of our solution. 
Result so far: 61259.7
Subtracting 4557 from 4910 leaves us with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Going ahead to step 10:
If we divide 3530 by 651, we get 5 and a remainder of 275.
The next digit of our result is 5. 
Result so far: 61259.75
Deduct 3255 from 3530 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 11:
651 can be fit into 2750 4 times, resulting in a remainder of 146.
The number 4 becomes the next digit in our result. 
Result so far: 61259.754
If we subtract 2604 from 2750, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 12:
651 goes into 1460 2 times with a remainder of 158.
The next digit of our result is 2. 
Result so far: 61259.7542
Subtract 1302 from 1460 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 13:
651 can be fit into 1580 2 times, resulting in a remainder of 278.
Write down 2 as next digit of the result. 
Result so far: 61259.75422
Subtracting 1302 from 1580 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

After the division, we end up with 61259.75422 and a remainder of 0.000278.
