Let's divide 66420 by 53
Our goal is to divide 66420 by 53.

Moving on to step 1:
53 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 53

Moving on to step 2:
53 goes into 66 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 53 from 66 to get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 53

On to step 3:
53 can be fit into 134 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 106 from 134 and we're left with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 53

On to step 4:
53 can be fit into 282 5 times, resulting in a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
If we subtract 265 from 282, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 53

On to step 5:
When dividing 170 by 53, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 1253.0
The remainder is 11 after subtracting 159 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 6:
The number 53 fits into 110 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1253.2
Subtract 106 from 110 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
When dividing 40 by 53, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1253.2
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
When dividing 400 by 53, we get 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 1253.207
Deduct 371 from 400 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
53 can be fit into 290 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 1253.2075
Deduct 265 from 290 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
When dividing 250 by 53, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 1253.20754
If we take 212 away from 250, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
The number 53 fits into 380 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 1253.207547
If we subtract 371 from 380, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
The number 53 fits into 90 1 times, leaving a remainder of 37.
The next digit of our result is 1. 
Result so far: 1253.2075471
If we subtract 53 from 90, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 13:
53 can be fit into 370 6 times, resulting in a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 1253.20754716
Subtracting 318 from 370 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 1253.20754716, and the remainder is 5.2e-08.
