We look at the division of 75641388 by 639 
Let's see how many times 639 fits into 75641388.

Advancing to step 1:
The number 639 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 639

Moving on to step 2:
When dividing 75 by 639, we get 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Take the next digit (6) from the dividend and append it to 75, then repeat: 756 / 639

Moving on to step 3:
639 goes into 756 1 times with a remainder of 117.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 639 from 756 leaves us with 117.
Bring next digit (4) of the dividend behind the 117 and repeat the process: 1174 / 639

Going ahead to step 4:
When dividing 1174 by 639, we get 1 with a remainder of 535.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 639 away from 1174, we end up with 535.
Bring next digit (1) of the dividend behind the 535 and repeat the process: 5351 / 639

Let's proceed to step 5:
639 can be fit into 5351 8 times, resulting in a remainder of 239.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
If we subtract 5112 from 5351, we get 239.
Fetch the next digit (3) from the dividend, attach it to 239 and continue: 2393 / 639

Let's proceed to step 6:
2393 divided by 639 is 3 with a remainder of 476.
The number 3 becomes the next digit in our result. 
Result so far: 1183.0
Subtract 1917 from 2393 to get 476.
Fetch the next digit (8) from the dividend, attach it to 476 and continue: 4768 / 639

Advancing to step 7:
4768 divided by 639 is 7 with a remainder of 295.
Record the quotient 7 as the next digit in the result. 
Result so far: 11837.0
Subtracting 4473 from 4768 leaves us with 295.
Include the next digit (8) from the dividend after 295, then repeat: 2958 / 639

On to step 8:
The number 639 fits into 2958 4 times, leaving a remainder of 402.
Write down 4 as next digit of the result. 
Result so far: 118374.0
Subtracting 2556 from 2958 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 9:
The number 639 fits into 4020 6 times, leaving a remainder of 186.
Use 6 as the next digit of our solution. 
Result so far: 118374.6
If we take 3834 away from 4020, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 10:
1860 divided by 639 is 2 with a remainder of 582.
Write down 2 as next digit of the result. 
Result so far: 118374.62
If we take 1278 away from 1860, we end up with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Let's proceed to step 11:
If we divide 5820 by 639, we get 9 and a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 118374.629
The remainder is 69 after subtracting 5751 from 5820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 12:
If we divide 690 by 639, we get 1 and a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 118374.6291
Subtract 639 from 690 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 13:
When dividing 510 by 639, we get 0 with a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 118374.6291
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 14:
When dividing 5100 by 639, we get 7 with a remainder of 627.
Put 7 as the next digit of the answer. 
Result so far: 118374.629107
Deduct 4473 from 5100 and we're left with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Let's proceed to step 15:
639 goes into 6270 9 times with a remainder of 519.
The next digit of our result is 9. 
Result so far: 118374.6291079
The remainder is 519 after subtracting 5751 from 6270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Moving on to step 16:
5190 divided by 639 is 8 with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 118374.62910798
If we take 5112 away from 5190, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 118374.62910798 with a balance of 7.8e-08.
