We're dividing 521444 by 51 
We want to figure out the number of times 521444 can be divided by 51.

On to step 1:
5 divided by 51 is 0 with 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.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 51

Advancing to step 2:
When dividing 52 by 51, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 51 from 52.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 51

Let's proceed to step 3:
If we divide 11 by 51, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 51

Going ahead to step 4:
When dividing 114 by 51, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 102.0
Deduct 102 from 114 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 51

Advancing to step 5:
51 goes into 124 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 1022.0
Deduct 102 from 124 and we're left with 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 51

Let's proceed to step 6:
The number 51 fits into 224 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 10224.0
Deduct 204 from 224 and we're left 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.

Going ahead to step 7:
200 divided by 51 is 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 10224.3
The remainder is 47 after subtracting 153 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 8:
If we divide 470 by 51, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 10224.39
If we take 459 away from 470, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
If we divide 110 by 51, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 10224.392
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 51, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 10224.3921
If we subtract 51 from 80, we 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.

Advancing to step 11:
The number 51 fits into 290 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 10224.39215
If we take 255 away from 290, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 10224.392156
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
51 goes into 440 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 10224.3921568
Deduct 408 from 440 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
51 can be fit into 320 6 times, resulting in a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 10224.39215686
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 10224.39215686, with a leftover of 1.4e-08.
