Let's divide 42719202 by 639
We want to divide 42719202 by 639.

Step 1:
The number 639 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 639

Let's proceed to step 2:
The number 639 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 639

Let's proceed to step 3:
The number 639 fits into 427 0 times, leaving a remainder of 427.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 427, we end up with 427.
Append the next digit (1) from the dividend to 427 and continue with: 4271 / 639

Step 4:
The number 639 fits into 4271 6 times, leaving a remainder of 437.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 3834 from 4271 and we're left with 437.
Take the next digit (9) from the dividend and append it to 437, then repeat: 4379 / 639

On to step 5:
4379 divided by 639 is 6 with a remainder of 545.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we subtract 3834 from 4379, we get 545.
Fetch the next digit (2) from the dividend, attach it to 545 and continue: 5452 / 639

Step 6:
When dividing 5452 by 639, we get 8 with a remainder of 340.
Put 8 as the next digit of the answer. 
Result so far: 668.0
The remainder is 340 after subtracting 5112 from 5452.
Fetch the next digit (0) from the dividend, attach it to 340 and continue: 3400 / 639

Going ahead to step 7:
639 can be fit into 3400 5 times, resulting in a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 6685.0
The remainder is 205 after subtracting 3195 from 3400.
Grab the next digit (2) from the dividend, add it to 205, then carry on: 2052 / 639

Moving on to step 8:
2052 divided by 639 is 3 with a remainder of 135.
Write down 3 as next digit of the result. 
Result so far: 66853.0
If we take 1917 away from 2052, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 9:
When dividing 1350 by 639, we get 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 66853.2
If we subtract 1278 from 1350, we 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.

Moving on to step 10:
639 can be fit into 720 1 times, resulting in a remainder of 81.
The next digit of our result is 1. 
Result so far: 66853.21
If we take 639 away from 720, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 11:
639 can be fit into 810 1 times, resulting in a remainder of 171.
Write down 1 as next digit of the result. 
Result so far: 66853.211
If we take 639 away from 810, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Our division results in 66853.211 with a remaining 0.0171.
