We're dividing 402398 by 53 
We want to figure out the number of times 402398 can be divided by 53.

Going ahead to step 1:
The number 53 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 53

Advancing to step 2:
When dividing 40 by 53, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 53

Going ahead to step 3:
The number 53 fits into 402 7 times, leaving a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 371 from 402, we get 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 53

Going ahead to step 4:
53 goes into 313 5 times with a remainder of 48.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we take 265 away from 313, we end up with 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 53

Step 5:
When dividing 489 by 53, we get 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 759.0
Subtracting 477 from 489 leaves us with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 53

Let's proceed to step 6:
If we divide 128 by 53, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 7592.0
If we subtract 106 from 128, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
53 can be fit into 220 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 7592.4
If we subtract 212 from 220, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
If we divide 80 by 53, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 7592.41
Deduct 53 from 80 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
270 divided by 53 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 7592.415
Subtracting 265 from 270 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
50 divided by 53 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 7592.415
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.

Step 11:
When dividing 500 by 53, we get 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 7592.41509
If we take 477 away from 500, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
53 goes into 230 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 7592.415094
The remainder is 18 after subtracting 212 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
53 can be fit into 180 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 7592.4150943
The remainder is 21 after subtracting 159 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 14:
If we divide 210 by 53, we get 3 and a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 7592.41509433
Deduct 159 from 210 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Our division results in 7592.41509433 with a remaining 5.1e-08.
