We look at the division of 82190321 by 42 
We want to divide 82190321 by 42.

Let's proceed to step 1:
The number 42 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 42

Let's proceed to step 2:
The number 42 fits into 82 1 times, leaving a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 42 from 82, we get 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 42

Step 3:
If we divide 401 by 42, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 378 from 401 and we're left with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 42

Advancing to step 4:
42 goes into 239 5 times with a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
Subtracting 210 from 239 leaves us with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 42

Going ahead to step 5:
The number 42 fits into 290 6 times, leaving a remainder of 38.
The next digit of our result is 6. 
Result so far: 1956.0
Subtracting 252 from 290 leaves us with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 42

Moving on to step 6:
42 can be fit into 383 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 19569.0
Subtract 378 from 383 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 42

Advancing to step 7:
52 divided by 42 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 195691.0
Deduct 42 from 52 and we're left with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 42

Advancing to step 8:
If we divide 101 by 42, we get 2 and a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 1956912.0
Subtracting 84 from 101 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
42 can be fit into 170 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1956912.4
If we take 168 away from 170, we end up with 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 10:
20 divided by 42 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 1956912.4
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.

Advancing to step 11:
If we divide 200 by 42, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 1956912.404
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
42 goes into 320 7 times with a remainder of 26.
The next digit of our result is 7. 
Result so far: 1956912.4047
If we take 294 away from 320, we end up with 26.
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 13:
260 divided by 42 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 1956912.40476
If we subtract 252 from 260, we 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 14:
If we divide 80 by 42, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1956912.404761
Subtracting 42 from 80 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 15:
42 goes into 380 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 1956912.4047619
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.

Going ahead to step 16:
42 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 1956912.4047619
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.

The quotient of the division is 1956912.4047619, and the remainder is 2e-08.
