We're dividing 251936 by 42 
We want to figure out the number of times 251936 can be divided by 42.

Step 1:
When dividing 2 by 42, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 42

Advancing to step 2:
42 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 42

Step 3:
42 can be fit into 251 5 times, resulting in a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 41 after subtracting 210 from 251.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 42

Going ahead to step 4:
When dividing 419 by 42, we get 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Subtract 378 from 419 to get 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 42

Advancing to step 5:
When dividing 413 by 42, we get 9 with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 599.0
Deduct 378 from 413 and we're left with 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 42

Going ahead to step 6:
If we divide 356 by 42, we get 8 and a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 5998.0
Subtracting 336 from 356 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
42 goes into 200 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 5998.4
If we take 168 away from 200, 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.

Moving on to step 8:
When dividing 320 by 42, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 5998.47
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
If we divide 260 by 42, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 5998.476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
42 goes into 80 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 5998.4761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
42 can be fit into 380 9 times, resulting in a remainder of 2.
The next digit of our result is 9. 
Result so far: 5998.47619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 5998.47619
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.

Step 13:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 5998.4761904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 5998.47619047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 5998.47619047 with a remaining 2.6e-08.
