Let's divide 55137546 by 639
We want to divide 55137546 by 639.

On to step 1:
639 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 639

On to step 2:
If we divide 55 by 639, we get 0 and a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 639

On to step 3:
551 divided by 639 is 0 with a remainder of 551.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 551, we end up with 551.
Bring next digit (3) of the dividend behind the 551 and repeat the process: 5513 / 639

Step 4:
639 goes into 5513 8 times with a remainder of 401.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 5112 from 5513 and we're left with 401.
Include the next digit (7) from the dividend after 401, then repeat: 4017 / 639

Moving on to step 5:
The number 639 fits into 4017 6 times, leaving a remainder of 183.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we subtract 3834 from 4017, we get 183.
Bring next digit (5) of the dividend behind the 183 and repeat the process: 1835 / 639

Going ahead to step 6:
639 can be fit into 1835 2 times, resulting in a remainder of 557.
Use 2 as the next digit of our solution. 
Result so far: 862.0
The remainder is 557 after subtracting 1278 from 1835.
Include the next digit (4) from the dividend after 557, then repeat: 5574 / 639

Let's proceed to step 7:
639 can be fit into 5574 8 times, resulting in a remainder of 462.
Put 8 as the next digit of the answer. 
Result so far: 8628.0
Subtracting 5112 from 5574 leaves us with 462.
Take the next digit (6) from the dividend and append it to 462, then repeat: 4626 / 639

On to step 8:
639 goes into 4626 7 times with a remainder of 153.
The next digit of our result is 7. 
Result so far: 86287.0
Subtract 4473 from 4626 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 9:
639 goes into 1530 2 times with a remainder of 252.
Use 2 as the next digit of our solution. 
Result so far: 86287.2
The remainder is 252 after subtracting 1278 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 10:
If we divide 2520 by 639, we get 3 and a remainder of 603.
Use 3 as the next digit of our solution. 
Result so far: 86287.23
The remainder is 603 after subtracting 1917 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Let's proceed to step 11:
639 can be fit into 6030 9 times, resulting in a remainder of 279.
Record the quotient 9 as the next digit in the result. 
Result so far: 86287.239
Subtracting 5751 from 6030 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 12:
639 goes into 2790 4 times with a remainder of 234.
Write down 4 as next digit of the result. 
Result so far: 86287.2394
The remainder is 234 after subtracting 2556 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 13:
2340 divided by 639 is 3 with a remainder of 423.
Use 3 as the next digit of our solution. 
Result so far: 86287.23943
Deduct 1917 from 2340 and we're left with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Advancing to step 14:
639 goes into 4230 6 times with a remainder of 396.
Use 6 as the next digit of our solution. 
Result so far: 86287.239436
Deduct 3834 from 4230 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 15:
The number 639 fits into 3960 6 times, leaving a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 86287.2394366
If we subtract 3834 from 3960, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final result is 86287.2394366 with a remainder of 1.26e-06.
