533421 ÷ 51 
Our goal is to divide 533421 by 51.

Advancing to step 1:
If we divide 5 by 51, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 51

On to step 2:
If we divide 53 by 51, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 51 from 53 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 51

Advancing to step 3:
51 can be fit into 23 0 times, resulting in a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 23 after subtracting 0 from 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 51

Step 4:
If we divide 234 by 51, we get 4 and a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we take 204 away from 234, we end up with 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 51

Moving on to step 5:
51 can be fit into 302 5 times, resulting in a remainder of 47.
The next digit of our result is 5. 
Result so far: 1045.0
The remainder is 47 after subtracting 255 from 302.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 51

Advancing to step 6:
When dividing 471 by 51, we get 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 10459.0
If we take 459 away from 471, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
When dividing 120 by 51, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 10459.2
The remainder is 18 after subtracting 102 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
When dividing 180 by 51, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 10459.23
Subtracting 153 from 180 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
The number 51 fits into 270 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 10459.235
If we take 255 away from 270, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
When dividing 150 by 51, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 10459.2352
Deduct 102 from 150 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
The number 51 fits into 480 9 times, leaving a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 10459.23529
If we subtract 459 from 480, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 12:
When dividing 210 by 51, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 10459.235294
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
If we divide 60 by 51, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 10459.2352941
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
51 can be fit into 90 1 times, resulting in a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 10459.23529411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 10459.23529411 with a remaining 3.9e-08.
