We look at the division of 51320 by 57 
We want to divide 51320 by 57.

Moving on to step 1:
The number 57 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 57

Moving on to step 2:
The number 57 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 57

Going ahead to step 3:
57 goes into 513 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 513 from 513 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 57

On to step 4:
When dividing 2 by 57, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 90.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 57

Let's proceed to step 5:
57 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 900.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 6:
If we divide 200 by 57, we get 3 and a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 900.3
Subtract 171 from 200 to get 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 7:
When dividing 290 by 57, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 900.35
If we take 285 away from 290, we end up 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.

Step 8:
57 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 900.35
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.

On to step 9:
57 can be fit into 500 8 times, resulting in a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 900.3508
Deduct 456 from 500 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
The number 57 fits into 440 7 times, leaving a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 900.35087
The remainder is 41 after subtracting 399 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 11:
If we divide 410 by 57, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 900.350877
Subtract 399 from 410 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 900.350877, with a leftover of 1.1e-06.
