We look at the division of 17522410 by 639 
Let's see how many times 639 fits into 17522410.

Step 1:
639 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 639

Step 2:
When dividing 17 by 639, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 639

On to step 3:
If we divide 175 by 639, we get 0 and a remainder of 175.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 175 and we're left with 175.
Bring next digit (2) of the dividend behind the 175 and repeat the process: 1752 / 639

Going ahead to step 4:
1752 divided by 639 is 2 with a remainder of 474.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1278 from 1752, we get 474.
Grab the next digit (2) from the dividend, add it to 474, then carry on: 4742 / 639

Advancing to step 5:
639 goes into 4742 7 times with a remainder of 269.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 4473 from 4742 to get 269.
Include the next digit (4) from the dividend after 269, then repeat: 2694 / 639

Going ahead to step 6:
If we divide 2694 by 639, we get 4 and a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 274.0
If we take 2556 away from 2694, we end up with 138.
Bring next digit (1) of the dividend behind the 138 and repeat the process: 1381 / 639

Advancing to step 7:
The number 639 fits into 1381 2 times, leaving a remainder of 103.
Use 2 as the next digit of our solution. 
Result so far: 2742.0
The remainder is 103 after subtracting 1278 from 1381.
Grab the next digit (0) from the dividend, add it to 103, then carry on: 1030 / 639

Moving on to step 8:
1030 divided by 639 is 1 with a remainder of 391.
Write down 1 as next digit of the result. 
Result so far: 27421.0
Subtract 639 from 1030 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 9:
If we divide 3910 by 639, we get 6 and a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 27421.6
Subtracting 3834 from 3910 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
760 divided by 639 is 1 with a remainder of 121.
The next digit of our result is 1. 
Result so far: 27421.61
Subtracting 639 from 760 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 11:
If we divide 1210 by 639, we get 1 and a remainder of 571.
The number 1 becomes the next digit in our result. 
Result so far: 27421.611
Deduct 639 from 1210 and we're left with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

The quotient of the division is 27421.611, and the remainder is 0.0571.
