638820 divided by 53 
We want to figure out the number of times 638820 can be divided by 53.

Moving on to step 1:
When dividing 6 by 53, we get 0 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.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 53

Step 2:
53 can be fit into 63 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 53 away from 63, we end up with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 53

Let's proceed to step 3:
53 can be fit into 108 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 106 from 108 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 53

On to step 4:
The number 53 fits into 28 0 times, leaving a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Subtract 0 from 28 to get 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 53

Going ahead to step 5:
If we divide 282 by 53, we get 5 and a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 1205.0
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

Step 6:
The number 53 fits into 170 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 12053.0
If we take 159 away from 170, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
53 goes into 110 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12053.2
Deduct 106 from 110 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 53 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12053.2
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
53 goes into 400 7 times with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 12053.207
If we take 371 away from 400, we end up 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.

Step 10:
290 divided by 53 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12053.2075
If we take 265 away from 290, we end up 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.

Going ahead to step 11:
53 goes into 250 4 times with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 12053.20754
The remainder is 38 after subtracting 212 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
The number 53 fits into 380 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 12053.207547
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.

On to step 13:
When dividing 90 by 53, we get 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 12053.2075471
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.

Step 14:
The number 53 fits into 370 6 times, leaving a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 12053.20754716
If we subtract 318 from 370, we get 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 12053.20754716, and the remainder is 5.2e-08.
