We look at the division of 51323052 by 802 
Let's see how many times 802 fits into 51323052.

Going ahead to step 1:
If we divide 5 by 802, we get 0 and 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 / 802

Step 2:
802 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
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 / 802

Going ahead to step 3:
When dividing 513 by 802, we get 0 with a remainder of 513.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 513 to get 513.
Append the next digit (2) from the dividend to 513 and continue with: 5132 / 802

Step 4:
If we divide 5132 by 802, we get 6 and a remainder of 320.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 4812 from 5132 to get 320.
Grab the next digit (3) from the dividend, add it to 320, then carry on: 3203 / 802

Advancing to step 5:
802 goes into 3203 3 times with a remainder of 797.
Write down 3 as next digit of the result. 
Result so far: 63.0
Deduct 2406 from 3203 and we're left with 797.
Grab the next digit (0) from the dividend, add it to 797, then carry on: 7970 / 802

Going ahead to step 6:
When dividing 7970 by 802, we get 9 with a remainder of 752.
Put 9 as the next digit of the answer. 
Result so far: 639.0
If we subtract 7218 from 7970, we get 752.
Append the next digit (5) from the dividend to 752 and continue with: 7525 / 802

Going ahead to step 7:
802 can be fit into 7525 9 times, resulting in a remainder of 307.
Use 9 as the next digit of our solution. 
Result so far: 6399.0
The remainder is 307 after subtracting 7218 from 7525.
Take the next digit (2) from the dividend and append it to 307, then repeat: 3072 / 802

Let's proceed to step 8:
802 goes into 3072 3 times with a remainder of 666.
Write down 3 as next digit of the result. 
Result so far: 63993.0
If we subtract 2406 from 3072, we get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Advancing to step 9:
6660 divided by 802 is 8 with a remainder of 244.
Use 8 as the next digit of our solution. 
Result so far: 63993.8
Deduct 6416 from 6660 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 10:
802 can be fit into 2440 3 times, resulting in a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 63993.83
If we take 2406 away from 2440, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
If we divide 340 by 802, we get 0 and a remainder of 340.
The next digit of our result is 0. 
Result so far: 63993.83
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 12:
802 can be fit into 3400 4 times, resulting in a remainder of 192.
Write down 4 as next digit of the result. 
Result so far: 63993.8304
Deduct 3208 from 3400 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 13:
When dividing 1920 by 802, we get 2 with a remainder of 316.
Write down 2 as next digit of the result. 
Result so far: 63993.83042
Subtracting 1604 from 1920 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 14:
802 can be fit into 3160 3 times, resulting in a remainder of 754.
The number 3 becomes the next digit in our result. 
Result so far: 63993.830423
If we subtract 2406 from 3160, we get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Let's proceed to step 15:
If we divide 7540 by 802, we get 9 and a remainder of 322.
Put 9 as the next digit of the answer. 
Result so far: 63993.8304239
If we take 7218 away from 7540, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 16:
The number 802 fits into 3220 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 63993.83042394
The remainder is 12 after subtracting 3208 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 63993.83042394 with a remainder of 1.2e-08.
