We look at the division of 9431672 by 639 
Let's see how many times 639 fits into 9431672.

Advancing to step 1:
If we divide 9 by 639, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 639

On to step 2:
639 goes into 94 0 times with a remainder of 94.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 94 to get 94.
Include the next digit (3) from the dividend after 94, then repeat: 943 / 639

Advancing to step 3:
When dividing 943 by 639, we get 1 with a remainder of 304.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 639 from 943 to get 304.
Include the next digit (1) from the dividend after 304, then repeat: 3041 / 639

Going ahead to step 4:
If we divide 3041 by 639, we get 4 and a remainder of 485.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 2556 from 3041 leaves us with 485.
Grab the next digit (6) from the dividend, add it to 485, then carry on: 4856 / 639

On to step 5:
When dividing 4856 by 639, we get 7 with a remainder of 383.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Deduct 4473 from 4856 and we're left with 383.
Fetch the next digit (7) from the dividend, attach it to 383 and continue: 3837 / 639

Step 6:
The number 639 fits into 3837 6 times, leaving a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 1476.0
Subtracting 3834 from 3837 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 639

Moving on to step 7:
When dividing 32 by 639, we get 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 14760.0
Subtract 0 from 32 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
639 goes into 320 0 times with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 14760.0
Deduct 0 from 320 and we're left 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.

Advancing to step 9:
When dividing 3200 by 639, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 14760.05
If we subtract 3195 from 3200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
The number 639 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 14760.05
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 11:
When dividing 500 by 639, we get 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 14760.05
Subtract 0 from 500 to 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.

After the division, we end up with 14760.05 and a remainder of 0.005.
