Let's divide 639723 by 53
We're looking to find how many times 53 goes into 639723.

On to step 1:
53 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 53

Moving on to step 2:
63 divided by 53 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 53 from 63 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 53

Let's proceed to step 3:
109 divided by 53 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 106 from 109 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 53

Moving on to step 4:
If we divide 37 by 53, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we take 0 away from 37, we end up with 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 53

On to step 5:
372 divided by 53 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1207.0
Subtracting 371 from 372 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 53

Step 6:
The number 53 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 12070.0
Subtracting 0 from 13 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
53 goes into 130 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 12070.2
Subtract 106 from 130 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
If we divide 240 by 53, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 12070.24
Subtracting 212 from 240 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
53 goes into 280 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 12070.245
Subtracting 265 from 280 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
150 divided by 53 is 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 12070.2452
Deduct 106 from 150 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
53 can be fit into 440 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 12070.24528
Subtract 424 from 440 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
53 can be fit into 160 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 12070.245283
Subtract 159 from 160 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
If we divide 10 by 53, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12070.245283
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
When dividing 100 by 53, we get 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 12070.24528301
Subtracting 53 from 100 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 12070.24528301 and a remainder of 4.7e-08.
