51426424 ÷ 51 
Let's see how many times 51 fits into 51426424.

On to step 1:
If we divide 5 by 51, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 51

Moving on to step 2:
When dividing 51 by 51, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 51 from 51.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 51

Let's proceed to step 3:
The number 51 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 51

Let's proceed to step 4:
The number 51 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 100.0
If we take 0 away from 42, we end up with 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 51

On to step 5:
If we divide 426 by 51, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 1008.0
Subtracting 408 from 426 leaves us with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 51

Advancing to step 6:
When dividing 184 by 51, we get 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 10083.0
If we subtract 153 from 184, we get 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 51

Step 7:
312 divided by 51 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 100836.0
If we subtract 306 from 312, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 51

Moving on to step 8:
51 goes into 64 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1008361.0
Deduct 51 from 64 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
51 goes into 130 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 1008361.2
Deduct 102 from 130 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
51 goes into 280 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1008361.25
If we take 255 away from 280, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
51 goes into 250 4 times with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 1008361.254
If we take 204 away from 250, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
51 can be fit into 460 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1008361.2549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
51 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1008361.2549
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
51 goes into 100 1 times with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 1008361.254901
If we take 51 away from 100, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 15:
When dividing 490 by 51, we get 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 1008361.2549019
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 16:
When dividing 310 by 51, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 1008361.25490196
Subtracting 306 from 310 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 1008361.25490196 with a remaining 4e-09.
