We look at the division of 51390075 by 53 
Our goal is to divide 51390075 by 53.

Advancing to step 1:
53 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 53

Step 2:
If we divide 51 by 53, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 53

Going ahead to step 3:
53 can be fit into 513 9 times, resulting in a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 477 from 513 and we're left with 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 53

Moving on to step 4:
53 can be fit into 369 6 times, resulting in a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Subtract 318 from 369 to get 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 53

Step 5:
53 can be fit into 510 9 times, resulting in a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 969.0
Subtract 477 from 510 to get 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 53

Let's proceed to step 6:
330 divided by 53 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 9696.0
If we take 318 away from 330, we end up with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 53

On to step 7:
53 can be fit into 127 2 times, resulting in a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 96962.0
Deduct 106 from 127 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 53

Going ahead to step 8:
53 goes into 215 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 969624.0
Subtracting 212 from 215 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
53 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 969624.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
The number 53 fits into 300 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 969624.05
Subtract 265 from 300 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
53 can be fit into 350 6 times, resulting in a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 969624.056
If we subtract 318 from 350, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
53 goes into 320 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 969624.0566
If we subtract 318 from 320, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 969624.0566 with a remaining 2e-05.
