We're dividing 51268194 by 124 
We want to divide 51268194 by 124.

On to step 1:
The number 124 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 124

Step 2:
51 divided by 124 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 124

Advancing to step 3:
124 goes into 512 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 16 after subtracting 496 from 512.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 124

Moving on to step 4:
124 can be fit into 166 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we subtract 124 from 166, we get 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 124

Step 5:
If we divide 428 by 124, we get 3 and a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 413.0
Deduct 372 from 428 and we're left with 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 124

Going ahead to step 6:
561 divided by 124 is 4 with a remainder of 65.
Record the quotient 4 as the next digit in the result. 
Result so far: 4134.0
Subtracting 496 from 561 leaves us with 65.
Grab the next digit (9) from the dividend, add it to 65, then carry on: 659 / 124

Going ahead to step 7:
124 can be fit into 659 5 times, resulting in a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 41345.0
Subtract 620 from 659 to get 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 124

Advancing to step 8:
The number 124 fits into 394 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 413453.0
The remainder is 22 after subtracting 372 from 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
If we divide 220 by 124, we get 1 and a remainder of 96.
Use 1 as the next digit of our solution. 
Result so far: 413453.1
The remainder is 96 after subtracting 124 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 10:
124 can be fit into 960 7 times, resulting in a remainder of 92.
Record the quotient 7 as the next digit in the result. 
Result so far: 413453.17
Subtracting 868 from 960 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 11:
124 can be fit into 920 7 times, resulting in a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 413453.177
Subtract 868 from 920 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 413453.177 and a remainder of 0.0052.
