Let's divide 109210 by 42
We're looking to find how many times 42 goes into 109210.

Moving on to step 1:
1 divided by 42 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 42

Let's proceed to step 2:
42 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 42

Going ahead to step 3:
42 can be fit into 109 2 times, resulting in a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 25 after subtracting 84 from 109.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 42

Step 4:
252 divided by 42 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 252 from 252 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 42

On to step 5:
The number 42 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 260.0
Subtract 0 from 1 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 42

On to step 6:
When dividing 10 by 42, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2600.0
The remainder is 10 after subtracting 0 from 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 7:
42 can be fit into 100 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2600.2
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 2600.23
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
340 divided by 42 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 2600.238
Subtracting 336 from 340 leaves us with 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:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2600.238
Subtract 0 from 40 to get 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.
Write down 9 as next digit of the result. 
Result so far: 2600.23809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2600.238095
Deduct 210 from 220 and we're left 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 13:
The number 42 fits into 100 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2600.2380952
If we subtract 84 from 100, we 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.

On to step 14:
If we divide 160 by 42, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 2600.23809523
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.

After the division, we end up with 2600.23809523 and a remainder of 3.4e-08.
