534437 ÷ 42 
We want to figure out the number of times 534437 can be divided by 42.

Step 1:
When dividing 5 by 42, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 42

Advancing to step 2:
53 divided by 42 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 42 from 53 and we're left with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 42

On to step 3:
If we divide 114 by 42, we get 2 and a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 84 from 114 to get 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 42

Advancing to step 4:
The number 42 fits into 304 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Subtract 294 from 304 to get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 42

On to step 5:
If we divide 103 by 42, we get 2 and a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 1272.0
Subtract 84 from 103 to get 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 42

Moving on to step 6:
197 divided by 42 is 4 with a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 12724.0
Subtracting 168 from 197 leaves us 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.

Step 7:
42 goes into 290 6 times with a remainder of 38.
The next digit of our result is 6. 
Result so far: 12724.6
Subtracting 252 from 290 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
If we divide 380 by 42, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 12724.69
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 42, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 12724.69
If we take 0 away from 20, we end up 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.

Step 10:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 12724.6904
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.

Step 11:
42 can be fit into 320 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 12724.69047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
260 divided by 42 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 12724.690476
If we take 252 away from 260, 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.

Advancing to step 13:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 12724.6904761
If we subtract 42 from 80, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
380 divided by 42 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 12724.69047619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 12724.69047619 with a remaining 2e-09.
