34246638 divided by 639 
We want to divide 34246638 by 639.

Let's proceed to step 1:
If we divide 3 by 639, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 639

Going ahead to step 2:
34 divided by 639 is 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 639

Advancing to step 3:
When dividing 342 by 639, we get 0 with a remainder of 342.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 342, we end up with 342.
Append the next digit (4) from the dividend to 342 and continue with: 3424 / 639

Step 4:
3424 divided by 639 is 5 with a remainder of 229.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 229 after subtracting 3195 from 3424.
Fetch the next digit (6) from the dividend, attach it to 229 and continue: 2296 / 639

Let's proceed to step 5:
When dividing 2296 by 639, we get 3 with a remainder of 379.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Deduct 1917 from 2296 and we're left with 379.
Take the next digit (6) from the dividend and append it to 379, then repeat: 3796 / 639

Going ahead to step 6:
The number 639 fits into 3796 5 times, leaving a remainder of 601.
The next digit of our result is 5. 
Result so far: 535.0
If we take 3195 away from 3796, we end up with 601.
Append the next digit (3) from the dividend to 601 and continue with: 6013 / 639

Advancing to step 7:
6013 divided by 639 is 9 with a remainder of 262.
The number 9 becomes the next digit in our result. 
Result so far: 5359.0
If we subtract 5751 from 6013, we get 262.
Grab the next digit (8) from the dividend, add it to 262, then carry on: 2628 / 639

Step 8:
639 can be fit into 2628 4 times, resulting in a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 53594.0
Subtract 2556 from 2628 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
The number 639 fits into 720 1 times, leaving a remainder of 81.
The next digit of our result is 1. 
Result so far: 53594.1
If we subtract 639 from 720, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 10:
639 goes into 810 1 times with a remainder of 171.
The number 1 becomes the next digit in our result. 
Result so far: 53594.11
The remainder is 171 after subtracting 639 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

After the division, we end up with 53594.11 and a remainder of 0.171.
