Let's divide 75380000 by 639
We're looking to find how many times 639 goes into 75380000.

Step 1:
When dividing 7 by 639, we get 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.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 639

On to step 2:
If we divide 75 by 639, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 639

Advancing to step 3:
When dividing 753 by 639, we get 1 with a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 639 from 753 to get 114.
Fetch the next digit (8) from the dividend, attach it to 114 and continue: 1148 / 639

On to step 4:
1148 divided by 639 is 1 with a remainder of 509.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 639 from 1148 and we're left with 509.
Include the next digit (0) from the dividend after 509, then repeat: 5090 / 639

Advancing to step 5:
639 goes into 5090 7 times with a remainder of 617.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Subtract 4473 from 5090 to get 617.
Fetch the next digit (0) from the dividend, attach it to 617 and continue: 6170 / 639

Let's proceed to step 6:
6170 divided by 639 is 9 with a remainder of 419.
The next digit of our result is 9. 
Result so far: 1179.0
The remainder is 419 after subtracting 5751 from 6170.
Include the next digit (0) from the dividend after 419, then repeat: 4190 / 639

Advancing to step 7:
639 can be fit into 4190 6 times, resulting in a remainder of 356.
The next digit of our result is 6. 
Result so far: 11796.0
If we subtract 3834 from 4190, we get 356.
Bring next digit (0) of the dividend behind the 356 and repeat the process: 3560 / 639

Step 8:
If we divide 3560 by 639, we get 5 and a remainder of 365.
Write down 5 as next digit of the result. 
Result so far: 117965.0
If we subtract 3195 from 3560, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 9:
When dividing 3650 by 639, we get 5 with a remainder of 455.
Use 5 as the next digit of our solution. 
Result so far: 117965.5
Subtract 3195 from 3650 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 10:
When dividing 4550 by 639, we get 7 with a remainder of 77.
The next digit of our result is 7. 
Result so far: 117965.57
Subtract 4473 from 4550 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 11:
770 divided by 639 is 1 with a remainder of 131.
Put 1 as the next digit of the answer. 
Result so far: 117965.571
If we take 639 away from 770, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 12:
If we divide 1310 by 639, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 117965.5712
Deduct 1278 from 1310 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
The number 639 fits into 320 0 times, leaving a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 117965.5712
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 14:
639 can be fit into 3200 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 117965.571205
Subtracting 3195 from 3200 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 15:
50 divided by 639 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 117965.571205
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 16:
639 can be fit into 500 0 times, resulting in a remainder of 500.
The next digit of our result is 0. 
Result so far: 117965.571205
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 117965.571205, with a leftover of 5e-07.
