We look at the division of 76293187 by 639 
We want to figure out the number of times 76293187 can be divided by 639.

Step 1:
The number 639 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 639

Step 2:
76 divided by 639 is 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 639

On to step 3:
When dividing 762 by 639, we get 1 with a remainder of 123.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 123 after subtracting 639 from 762.
Append the next digit (9) from the dividend to 123 and continue with: 1239 / 639

Moving on to step 4:
639 can be fit into 1239 1 times, resulting in a remainder of 600.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 639 from 1239 and we're left with 600.
Take the next digit (3) from the dividend and append it to 600, then repeat: 6003 / 639

Let's proceed to step 5:
639 can be fit into 6003 9 times, resulting in a remainder of 252.
The next digit of our result is 9. 
Result so far: 119.0
Subtracting 5751 from 6003 leaves us with 252.
Take the next digit (1) from the dividend and append it to 252, then repeat: 2521 / 639

Moving on to step 6:
If we divide 2521 by 639, we get 3 and a remainder of 604.
Record the quotient 3 as the next digit in the result. 
Result so far: 1193.0
If we subtract 1917 from 2521, we get 604.
Include the next digit (8) from the dividend after 604, then repeat: 6048 / 639

Step 7:
6048 divided by 639 is 9 with a remainder of 297.
Write down 9 as next digit of the result. 
Result so far: 11939.0
Deduct 5751 from 6048 and we're left with 297.
Bring next digit (7) of the dividend behind the 297 and repeat the process: 2977 / 639

Moving on to step 8:
639 goes into 2977 4 times with a remainder of 421.
The number 4 becomes the next digit in our result. 
Result so far: 119394.0
Subtract 2556 from 2977 to get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Going ahead to step 9:
639 can be fit into 4210 6 times, resulting in a remainder of 376.
Record the quotient 6 as the next digit in the result. 
Result so far: 119394.6
If we subtract 3834 from 4210, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 10:
639 goes into 3760 5 times with a remainder of 565.
Record the quotient 5 as the next digit in the result. 
Result so far: 119394.65
If we subtract 3195 from 3760, we get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Moving on to step 11:
639 can be fit into 5650 8 times, resulting in a remainder of 538.
Use 8 as the next digit of our solution. 
Result so far: 119394.658
If we take 5112 away from 5650, we end up with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Moving on to step 12:
The number 639 fits into 5380 8 times, leaving a remainder of 268.
The number 8 becomes the next digit in our result. 
Result so far: 119394.6588
Subtract 5112 from 5380 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

In conclusion, the division gives 119394.6588 with a balance of 0.00268.
