We're dividing 4783147 by 639 
We're looking to find how many times 639 goes into 4783147.

Let's proceed to step 1:
4 divided by 639 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 639

Step 2:
47 divided by 639 is 0 with a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 639

Advancing to step 3:
639 can be fit into 478 0 times, resulting in a remainder of 478.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 478 and we're left with 478.
Append the next digit (3) from the dividend to 478 and continue with: 4783 / 639

Step 4:
The number 639 fits into 4783 7 times, leaving a remainder of 310.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 310 after subtracting 4473 from 4783.
Take the next digit (1) from the dividend and append it to 310, then repeat: 3101 / 639

On to step 5:
3101 divided by 639 is 4 with a remainder of 545.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 2556 from 3101 leaves us with 545.
Take the next digit (4) from the dividend and append it to 545, then repeat: 5454 / 639

Moving on to step 6:
If we divide 5454 by 639, we get 8 and a remainder of 342.
Write down 8 as next digit of the result. 
Result so far: 748.0
If we subtract 5112 from 5454, we get 342.
Append the next digit (7) from the dividend to 342 and continue with: 3427 / 639

Advancing to step 7:
When dividing 3427 by 639, we get 5 with a remainder of 232.
Record the quotient 5 as the next digit in the result. 
Result so far: 7485.0
The remainder is 232 after subtracting 3195 from 3427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 8:
2320 divided by 639 is 3 with a remainder of 403.
Use 3 as the next digit of our solution. 
Result so far: 7485.3
The remainder is 403 after subtracting 1917 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

On to step 9:
When dividing 4030 by 639, we get 6 with a remainder of 196.
Write down 6 as next digit of the result. 
Result so far: 7485.36
Deduct 3834 from 4030 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 10:
639 goes into 1960 3 times with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 7485.363
If we subtract 1917 from 1960, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 11:
If we divide 430 by 639, we get 0 and a remainder of 430.
Record the quotient 0 as the next digit in the result. 
Result so far: 7485.363
The remainder is 430 after subtracting 0 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 12:
The number 639 fits into 4300 6 times, leaving a remainder of 466.
Put 6 as the next digit of the answer. 
Result so far: 7485.36306
Deduct 3834 from 4300 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 13:
If we divide 4660 by 639, we get 7 and a remainder of 187.
Write down 7 as next digit of the result. 
Result so far: 7485.363067
Subtract 4473 from 4660 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 14:
639 goes into 1870 2 times with a remainder of 592.
Put 2 as the next digit of the answer. 
Result so far: 7485.3630672
Subtracting 1278 from 1870 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 15:
639 goes into 5920 9 times with a remainder of 169.
Put 9 as the next digit of the answer. 
Result so far: 7485.36306729
Subtract 5751 from 5920 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

The final result is 7485.36306729 with a remainder of 1.69e-07.
