Let's divide 124231 by 51
We want to figure out the number of times 124231 can be divided by 51.

Moving on 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
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 51

On to step 2:
51 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 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.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 102 away from 124, we end up with 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 51

Advancing to step 4:
When dividing 222 by 51, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 204 away from 222, we end up with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 51

Advancing to step 5:
If we divide 183 by 51, we get 3 and a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 243.0
If we subtract 153 from 183, we get 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 51

On to step 6:
301 divided by 51 is 5 with a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 2435.0
Subtract 255 from 301 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
460 divided by 51 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 2435.9
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.

Moving on to step 8:
51 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2435.9
If we take 0 away from 10, we end up with 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 9:
When dividing 100 by 51, we get 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 2435.901
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.

On to step 10:
51 goes into 490 9 times with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 2435.9019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 11:
310 divided by 51 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 2435.90196
If we subtract 306 from 310, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
When dividing 40 by 51, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 2435.90196
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
If we divide 400 by 51, we get 7 and a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 2435.9019607
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 14:
51 goes into 430 8 times with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 2435.90196078
The remainder is 22 after subtracting 408 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 2435.90196078 with a remaining 2.2e-08.
