124152 divided by 51 
We're looking to find how many times 51 goes into 124152.

Step 1:
51 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 51

On to step 2:
12 divided by 51 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 51

Moving on to step 3:
124 divided by 51 is 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 102 from 124 leaves us with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 51

Advancing to step 4:
If we divide 221 by 51, we get 4 and a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 204 from 221, we get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 51

Advancing to step 5:
When dividing 175 by 51, we get 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 243.0
Subtract 153 from 175 to get 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 51

Going ahead to step 6:
222 divided by 51 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 2434.0
Subtracting 204 from 222 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
The number 51 fits into 180 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 2434.3
If we subtract 153 from 180, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
51 goes into 270 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 2434.35
The remainder is 15 after subtracting 255 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
51 can be fit into 150 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 2434.352
Subtract 102 from 150 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
480 divided by 51 is 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 2434.3529
Subtract 459 from 480 to 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.

Advancing to step 11:
When dividing 210 by 51, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 2434.35294
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
If we divide 60 by 51, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 2434.352941
Subtracting 51 from 60 leaves us 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.

Moving on to step 13:
90 divided by 51 is 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 2434.3529411
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 2434.3529411, with a leftover of 3.9e-07.
