123524 ÷ 51 
We're looking to find how many times 51 goes into 123524.

Going ahead to step 1:
When dividing 1 by 51, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 51

Step 2:
If we divide 12 by 51, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 51

Let's proceed to step 3:
If we divide 123 by 51, we get 2 and a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 102 from 123, we get 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 51

Let's proceed to step 4:
If we divide 215 by 51, we get 4 and a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 204 from 215, we get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 51

On to step 5:
When dividing 112 by 51, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 242.0
If we subtract 102 from 112, we get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 51

Advancing to step 6:
When dividing 104 by 51, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2422.0
If we take 102 away from 104, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
20 divided by 51 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2422.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
51 can be fit into 200 3 times, resulting in a remainder of 47.
The next digit of our result is 3. 
Result so far: 2422.03
Subtracting 153 from 200 leaves us with 47.
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 9:
470 divided by 51 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 2422.039
Deduct 459 from 470 and we're left 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.

On to step 10:
The number 51 fits into 110 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2422.0392
If we take 102 away from 110, we end up 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.

Going ahead to step 11:
51 goes into 80 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 2422.03921
If we take 51 away from 80, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
51 can be fit into 290 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 2422.039215
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 13:
51 can be fit into 350 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 2422.0392156
Subtract 306 from 350 to 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.

Let's proceed to step 14:
440 divided by 51 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 2422.03921568
If we take 408 away from 440, we end up 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.

The final result is 2422.03921568 with a remainder of 3.2e-08.
