198579 divided by 42 
We want to divide 198579 by 42.

Going ahead to step 1:
1 divided by 42 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 42

Moving on to step 2:
19 divided by 42 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 42

Let's proceed to step 3:
42 can be fit into 198 4 times, resulting in a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 30 after subtracting 168 from 198.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 42

Step 4:
When dividing 305 by 42, we get 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 47.0
The remainder is 11 after subtracting 294 from 305.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 42

Advancing to step 5:
42 goes into 117 2 times with a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 472.0
Subtracting 84 from 117 leaves us with 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 42

Let's proceed to step 6:
339 divided by 42 is 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 4728.0
If we subtract 336 from 339, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
42 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4728.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
When dividing 300 by 42, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 4728.07
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
When dividing 60 by 42, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 4728.071
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
42 goes into 180 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4728.0714
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
When dividing 120 by 42, we get 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 4728.07142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 4728.071428
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
240 divided by 42 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 4728.0714285
Deduct 210 from 240 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 4728.07142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 4728.07142857, and the remainder is 6e-09.
