755170 divided by 42 
Our goal is to divide 755170 by 42.

Let's proceed to step 1:
If we divide 7 by 42, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 42

Advancing to step 2:
The number 42 fits into 75 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 75 and we're left with 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 42

Going ahead to step 3:
42 can be fit into 335 7 times, resulting in a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 294 away from 335, we end up with 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 42

Moving on to step 4:
When dividing 411 by 42, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 179.0
Subtract 378 from 411 to get 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 42

Let's proceed to step 5:
The number 42 fits into 337 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 1798.0
If we take 336 away from 337, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 42

On to step 6:
If we divide 10 by 42, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 17980.0
Subtracting 0 from 10 leaves us 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.

Advancing to step 7:
When dividing 100 by 42, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 17980.2
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
If we divide 160 by 42, we get 3 and a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 17980.23
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
42 goes into 340 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 17980.238
Subtract 336 from 340 to 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 10:
If we divide 40 by 42, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 17980.238
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.

Moving on to step 11:
42 goes into 400 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 17980.23809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 17980.238095
Subtracting 210 from 220 leaves us 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.

On to step 13:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 17980.2380952
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
42 can be fit into 160 3 times, resulting in a remainder of 34.
The next digit of our result is 3. 
Result so far: 17980.23809523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 17980.23809523, with a leftover of 3.4e-08.
