We look at the division of 51502490 by 322 
We want to divide 51502490 by 322.

Going ahead to step 1:
322 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 take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 322

Going ahead to step 2:
322 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 322

Going ahead to step 3:
When dividing 515 by 322, we get 1 with a remainder of 193.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 322 from 515 and we're left with 193.
Include the next digit (0) from the dividend after 193, then repeat: 1930 / 322

Moving on to step 4:
322 goes into 1930 5 times with a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 1610 away from 1930, we end up with 320.
Include the next digit (2) from the dividend after 320, then repeat: 3202 / 322

On to step 5:
322 goes into 3202 9 times with a remainder of 304.
Write down 9 as next digit of the result. 
Result so far: 159.0
Subtracting 2898 from 3202 leaves us with 304.
Grab the next digit (4) from the dividend, add it to 304, then carry on: 3044 / 322

Advancing to step 6:
322 goes into 3044 9 times with a remainder of 146.
Record the quotient 9 as the next digit in the result. 
Result so far: 1599.0
Subtracting 2898 from 3044 leaves us with 146.
Include the next digit (9) from the dividend after 146, then repeat: 1469 / 322

Step 7:
322 can be fit into 1469 4 times, resulting in a remainder of 181.
Put 4 as the next digit of the answer. 
Result so far: 15994.0
If we take 1288 away from 1469, we end up with 181.
Include the next digit (0) from the dividend after 181, then repeat: 1810 / 322

Going ahead to step 8:
322 goes into 1810 5 times with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 159945.0
If we take 1610 away from 1810, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 9:
2000 divided by 322 is 6 with a remainder of 68.
The next digit of our result is 6. 
Result so far: 159945.6
Subtracting 1932 from 2000 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 10:
680 divided by 322 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 159945.62
The remainder is 36 after subtracting 644 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
If we divide 360 by 322, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 159945.621
Subtracting 322 from 360 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
380 divided by 322 is 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 159945.6211
If we take 322 away from 380, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 159945.6211 and a remainder of 0.00058.
