Let's divide 53552151 by 639
Our goal is to divide 53552151 by 639.

Going ahead to step 1:
The number 639 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 639

Moving on to step 2:
53 divided by 639 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 639

Going ahead to step 3:
When dividing 535 by 639, we get 0 with a remainder of 535.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 535 after subtracting 0 from 535.
Fetch the next digit (5) from the dividend, attach it to 535 and continue: 5355 / 639

On to step 4:
The number 639 fits into 5355 8 times, leaving a remainder of 243.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 5112 from 5355 and we're left with 243.
Append the next digit (2) from the dividend to 243 and continue with: 2432 / 639

Going ahead to step 5:
The number 639 fits into 2432 3 times, leaving a remainder of 515.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
The remainder is 515 after subtracting 1917 from 2432.
Take the next digit (1) from the dividend and append it to 515, then repeat: 5151 / 639

Advancing to step 6:
5151 divided by 639 is 8 with a remainder of 39.
The next digit of our result is 8. 
Result so far: 838.0
Deduct 5112 from 5151 and we're left with 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 639

Step 7:
395 divided by 639 is 0 with a remainder of 395.
Use 0 as the next digit of our solution. 
Result so far: 8380.0
If we subtract 0 from 395, we get 395.
Bring next digit (1) of the dividend behind the 395 and repeat the process: 3951 / 639

Advancing to step 8:
3951 divided by 639 is 6 with a remainder of 117.
The next digit of our result is 6. 
Result so far: 83806.0
The remainder is 117 after subtracting 3834 from 3951.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 9:
The number 639 fits into 1170 1 times, leaving a remainder of 531.
Write down 1 as next digit of the result. 
Result so far: 83806.1
If we take 639 away from 1170, we end up with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 10:
639 goes into 5310 8 times with a remainder of 198.
Write down 8 as next digit of the result. 
Result so far: 83806.18
If we take 5112 away from 5310, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 11:
639 goes into 1980 3 times with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 83806.183
If we subtract 1917 from 1980, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 12:
If we divide 630 by 639, we get 0 and a remainder of 630.
Use 0 as the next digit of our solution. 
Result so far: 83806.183
Deduct 0 from 630 and we're left with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 13:
The number 639 fits into 6300 9 times, leaving a remainder of 549.
Write down 9 as next digit of the result. 
Result so far: 83806.18309
If we subtract 5751 from 6300, we get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Step 14:
The number 639 fits into 5490 8 times, leaving a remainder of 378.
Put 8 as the next digit of the answer. 
Result so far: 83806.183098
If we subtract 5112 from 5490, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 15:
If we divide 3780 by 639, we get 5 and a remainder of 585.
The next digit of our result is 5. 
Result so far: 83806.1830985
Subtracting 3195 from 3780 leaves us with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 16:
When dividing 5850 by 639, we get 9 with a remainder of 99.
The next digit of our result is 9. 
Result so far: 83806.18309859
Subtracting 5751 from 5850 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Our division results in 83806.18309859 with a remaining 9.9e-08.
