We divide 12179240 by 639
We want to divide 12179240 by 639.

Going ahead to step 1:
639 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 639

On to step 2:
If we divide 12 by 639, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 639

Moving on to step 3:
When dividing 121 by 639, we get 0 with a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 121, we get 121.
Fetch the next digit (7) from the dividend, attach it to 121 and continue: 1217 / 639

Advancing to step 4:
The number 639 fits into 1217 1 times, leaving a remainder of 578.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 639 from 1217, we get 578.
Fetch the next digit (9) from the dividend, attach it to 578 and continue: 5789 / 639

Advancing to step 5:
639 goes into 5789 9 times with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 5751 away from 5789, we end up with 38.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 639

Advancing to step 6:
If we divide 382 by 639, we get 0 and a remainder of 382.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
Subtract 0 from 382 to get 382.
Append the next digit (4) from the dividend to 382 and continue with: 3824 / 639

Step 7:
639 goes into 3824 5 times with a remainder of 629.
The next digit of our result is 5. 
Result so far: 1905.0
The remainder is 629 after subtracting 3195 from 3824.
Bring next digit (0) of the dividend behind the 629 and repeat the process: 6290 / 639

Going ahead to step 8:
When dividing 6290 by 639, we get 9 with a remainder of 539.
Write down 9 as next digit of the result. 
Result so far: 19059.0
Subtract 5751 from 6290 to get 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Let's proceed to step 9:
5390 divided by 639 is 8 with a remainder of 278.
Put 8 as the next digit of the answer. 
Result so far: 19059.8
Subtract 5112 from 5390 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 10:
The number 639 fits into 2780 4 times, leaving a remainder of 224.
Use 4 as the next digit of our solution. 
Result so far: 19059.84
Deduct 2556 from 2780 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 11:
The number 639 fits into 2240 3 times, leaving a remainder of 323.
Put 3 as the next digit of the answer. 
Result so far: 19059.843
The remainder is 323 after subtracting 1917 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 12:
The number 639 fits into 3230 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 19059.8435
Subtract 3195 from 3230 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
The number 639 fits into 350 0 times, leaving a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 19059.8435
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 14:
When dividing 3500 by 639, we get 5 with a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 19059.843505
Subtract 3195 from 3500 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 15:
3050 divided by 639 is 4 with a remainder of 494.
Write down 4 as next digit of the result. 
Result so far: 19059.8435054
The remainder is 494 after subtracting 2556 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Going ahead to step 16:
When dividing 4940 by 639, we get 7 with a remainder of 467.
Use 7 as the next digit of our solution. 
Result so far: 19059.84350547
The remainder is 467 after subtracting 4473 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

The quotient of the division is 19059.84350547, and the remainder is 4.67e-07.
