51470985 ÷ 285 
Our goal is to divide 51470985 by 285.

On to step 1:
285 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 285

On to step 2:
285 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 285

Step 3:
514 divided by 285 is 1 with a remainder of 229.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 229 after subtracting 285 from 514.
Fetch the next digit (7) from the dividend, attach it to 229 and continue: 2297 / 285

Step 4:
285 goes into 2297 8 times with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 2280 from 2297 to get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 285

Going ahead to step 5:
285 can be fit into 170 0 times, resulting in a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 180.0
If we take 0 away from 170, we end up with 170.
Bring next digit (9) of the dividend behind the 170 and repeat the process: 1709 / 285

On to step 6:
If we divide 1709 by 285, we get 5 and a remainder of 284.
Put 5 as the next digit of the answer. 
Result so far: 1805.0
Deduct 1425 from 1709 and we're left with 284.
Fetch the next digit (8) from the dividend, attach it to 284 and continue: 2848 / 285

Advancing to step 7:
285 can be fit into 2848 9 times, resulting in a remainder of 283.
Write down 9 as next digit of the result. 
Result so far: 18059.0
If we take 2565 away from 2848, we end up with 283.
Bring next digit (5) of the dividend behind the 283 and repeat the process: 2835 / 285

Moving on to step 8:
When dividing 2835 by 285, we get 9 with a remainder of 270.
Write down 9 as next digit of the result. 
Result so far: 180599.0
If we subtract 2565 from 2835, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 9:
When dividing 2700 by 285, we get 9 with a remainder of 135.
The next digit of our result is 9. 
Result so far: 180599.9
Subtract 2565 from 2700 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 10:
285 goes into 1350 4 times with a remainder of 210.
Put 4 as the next digit of the answer. 
Result so far: 180599.94
Subtracting 1140 from 1350 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 11:
285 can be fit into 2100 7 times, resulting in a remainder of 105.
Write down 7 as next digit of the result. 
Result so far: 180599.947
Subtract 1995 from 2100 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 12:
The number 285 fits into 1050 3 times, leaving a remainder of 195.
Record the quotient 3 as the next digit in the result. 
Result so far: 180599.9473
The remainder is 195 after subtracting 855 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 13:
285 can be fit into 1950 6 times, resulting in a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 180599.94736
If we take 1710 away from 1950, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 14:
285 goes into 2400 8 times with a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 180599.947368
Subtract 2280 from 2400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
The number 285 fits into 1200 4 times, leaving a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 180599.9473684
If we take 1140 away from 1200, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 16:
285 goes into 600 2 times with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 180599.94736842
Deduct 570 from 600 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 180599.94736842 with a remaining 3e-08.
