We look at the division of 51381208 by 53 
We want to divide 51381208 by 53.

Let's proceed to step 1:
53 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 53

On to step 2:
When dividing 51 by 53, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 53

Moving on to step 3:
53 goes into 513 9 times with a remainder of 36.
The next digit of our result is 9. 
Result so far: 9.0
If we take 477 away from 513, we end up with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 53

Let's proceed to step 4:
If we divide 368 by 53, we get 6 and a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we take 318 away from 368, we end up with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 53

On to step 5:
53 can be fit into 501 9 times, resulting in a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 969.0
The remainder is 24 after subtracting 477 from 501.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 53

On to step 6:
53 goes into 242 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 9694.0
Deduct 212 from 242 and we're left with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 53

Advancing to step 7:
300 divided by 53 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 96945.0
The remainder is 35 after subtracting 265 from 300.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 53

Step 8:
When dividing 358 by 53, we get 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 969456.0
Subtract 318 from 358 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.

On to step 9:
400 divided by 53 is 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 969456.7
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.

Moving on to step 10:
When dividing 290 by 53, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 969456.75
The remainder is 25 after subtracting 265 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
53 can be fit into 250 4 times, resulting in a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 969456.754
Subtract 212 from 250 to get 38.
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.
Put 7 as the next digit of the answer. 
Result so far: 969456.7547
The remainder is 9 after subtracting 371 from 380.
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 13:
The number 53 fits into 90 1 times, leaving a remainder of 37.
The next digit of our result is 1. 
Result so far: 969456.75471
If we take 53 away from 90, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 14:
53 can be fit into 370 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 969456.754716
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.

Advancing to step 15:
520 divided by 53 is 9 with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 969456.7547169
Subtracting 477 from 520 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 16:
430 divided by 53 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 969456.75471698
Subtract 424 from 430 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 969456.75471698, with a leftover of 6e-09.
