41012845 divided by 639 
Our goal is to divide 41012845 by 639.

Going ahead to step 1:
The number 639 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 639

Going ahead to step 2:
639 can be fit into 41 0 times, resulting in a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 41 and we're left with 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 639

Advancing to step 3:
639 goes into 410 0 times with a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 410, we end up with 410.
Bring next digit (1) of the dividend behind the 410 and repeat the process: 4101 / 639

Moving on to step 4:
639 goes into 4101 6 times with a remainder of 267.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 3834 from 4101, we get 267.
Bring next digit (2) of the dividend behind the 267 and repeat the process: 2672 / 639

Moving on to step 5:
639 can be fit into 2672 4 times, resulting in a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we take 2556 away from 2672, we end up with 116.
Grab the next digit (8) from the dividend, add it to 116, then carry on: 1168 / 639

Advancing to step 6:
When dividing 1168 by 639, we get 1 with a remainder of 529.
The number 1 becomes the next digit in our result. 
Result so far: 641.0
If we take 639 away from 1168, we end up with 529.
Bring next digit (4) of the dividend behind the 529 and repeat the process: 5294 / 639

Moving on to step 7:
If we divide 5294 by 639, we get 8 and a remainder of 182.
The next digit of our result is 8. 
Result so far: 6418.0
Deduct 5112 from 5294 and we're left with 182.
Append the next digit (5) from the dividend to 182 and continue with: 1825 / 639

Step 8:
When dividing 1825 by 639, we get 2 with a remainder of 547.
Put 2 as the next digit of the answer. 
Result so far: 64182.0
If we subtract 1278 from 1825, we get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Going ahead to step 9:
639 goes into 5470 8 times with a remainder of 358.
The next digit of our result is 8. 
Result so far: 64182.8
Subtract 5112 from 5470 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 10:
When dividing 3580 by 639, we get 5 with a remainder of 385.
Write down 5 as next digit of the result. 
Result so far: 64182.85
Subtracting 3195 from 3580 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 11:
If we divide 3850 by 639, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 64182.856
Deduct 3834 from 3850 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
639 can be fit into 160 0 times, resulting in a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 64182.856
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
639 can be fit into 1600 2 times, resulting in a remainder of 322.
The number 2 becomes the next digit in our result. 
Result so far: 64182.85602
If we take 1278 away from 1600, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 14:
The number 639 fits into 3220 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 64182.856025
If we subtract 3195 from 3220, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 15:
639 can be fit into 250 0 times, resulting in a remainder of 250.
The next digit of our result is 0. 
Result so far: 64182.856025
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 16:
When dividing 2500 by 639, we get 3 with a remainder of 583.
Put 3 as the next digit of the answer. 
Result so far: 64182.85602503
Subtract 1917 from 2500 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

The final outcome is 64182.85602503, with a leftover of 5.83e-07.
