We divide 74810568 by 639
We want to divide 74810568 by 639.

Let's proceed to step 1:
7 divided by 639 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 639

On to step 2:
639 goes into 74 0 times with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Append the next digit (8) from the dividend to 74 and continue with: 748 / 639

Step 3:
If we divide 748 by 639, we get 1 and a remainder of 109.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 639 from 748 to get 109.
Fetch the next digit (1) from the dividend, attach it to 109 and continue: 1091 / 639

Moving on to step 4:
The number 639 fits into 1091 1 times, leaving a remainder of 452.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 639 from 1091 to get 452.
Bring next digit (0) of the dividend behind the 452 and repeat the process: 4520 / 639

Moving on to step 5:
The number 639 fits into 4520 7 times, leaving a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we subtract 4473 from 4520, we get 47.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 639

Let's proceed to step 6:
639 can be fit into 475 0 times, resulting in a remainder of 475.
Write down 0 as next digit of the result. 
Result so far: 1170.0
Subtract 0 from 475 to get 475.
Append the next digit (6) from the dividend to 475 and continue with: 4756 / 639

Step 7:
When dividing 4756 by 639, we get 7 with a remainder of 283.
The next digit of our result is 7. 
Result so far: 11707.0
Subtracting 4473 from 4756 leaves us with 283.
Fetch the next digit (8) from the dividend, attach it to 283 and continue: 2838 / 639

Going ahead to step 8:
639 goes into 2838 4 times with a remainder of 282.
The number 4 becomes the next digit in our result. 
Result so far: 117074.0
Subtracting 2556 from 2838 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 9:
2820 divided by 639 is 4 with a remainder of 264.
Record the quotient 4 as the next digit in the result. 
Result so far: 117074.4
Subtract 2556 from 2820 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 10:
639 can be fit into 2640 4 times, resulting in a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 117074.44
Subtract 2556 from 2640 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 117074.44 with a remaining 0.084.
