We look at the division of 51390707 by 570 
Our goal is to divide 51390707 by 570.

Step 1:
5 divided by 570 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 570

Advancing to step 2:
570 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 570

Let's proceed to step 3:
513 divided by 570 is 0 with a remainder of 513.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 513 leaves us with 513.
Append the next digit (9) from the dividend to 513 and continue with: 5139 / 570

Moving on to step 4:
570 can be fit into 5139 9 times, resulting in a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 5130 from 5139, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 570

Advancing to step 5:
If we divide 90 by 570, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 90.0
Subtracting 0 from 90 leaves us with 90.
Bring next digit (7) of the dividend behind the 90 and repeat the process: 907 / 570

Advancing to step 6:
570 goes into 907 1 times with a remainder of 337.
Write down 1 as next digit of the result. 
Result so far: 901.0
Deduct 570 from 907 and we're left with 337.
Bring next digit (0) of the dividend behind the 337 and repeat the process: 3370 / 570

Step 7:
When dividing 3370 by 570, we get 5 with a remainder of 520.
Write down 5 as next digit of the result. 
Result so far: 9015.0
The remainder is 520 after subtracting 2850 from 3370.
Fetch the next digit (7) from the dividend, attach it to 520 and continue: 5207 / 570

On to step 8:
When dividing 5207 by 570, we get 9 with a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 90159.0
Subtracting 5130 from 5207 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
570 goes into 770 1 times with a remainder of 200.
Put 1 as the next digit of the answer. 
Result so far: 90159.1
If we subtract 570 from 770, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
2000 divided by 570 is 3 with a remainder of 290.
The next digit of our result is 3. 
Result so far: 90159.13
Subtract 1710 from 2000 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 11:
570 can be fit into 2900 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 90159.135
Subtracting 2850 from 2900 leaves us 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.

Moving on to step 12:
The number 570 fits into 500 0 times, leaving a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 90159.135
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 13:
570 goes into 5000 8 times with a remainder of 440.
Put 8 as the next digit of the answer. 
Result so far: 90159.13508
Deduct 4560 from 5000 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 14:
If we divide 4400 by 570, we get 7 and a remainder of 410.
The number 7 becomes the next digit in our result. 
Result so far: 90159.135087
Subtract 3990 from 4400 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 15:
4100 divided by 570 is 7 with a remainder of 110.
The number 7 becomes the next digit in our result. 
Result so far: 90159.1350877
The remainder is 110 after subtracting 3990 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final outcome is 90159.1350877, with a leftover of 1.1e-06.
