Let's divide 158098 by 42
Our goal is to divide 158098 by 42.

Step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 42

Step 2:
42 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 42

On to step 3:
When dividing 158 by 42, we get 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 126 from 158 and we're left with 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 42

Moving on to step 4:
320 divided by 42 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 294 away from 320, we end up with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 42

On to step 5:
When dividing 269 by 42, we get 6 with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 376.0
If we subtract 252 from 269, we get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 42

Let's proceed to step 6:
42 goes into 178 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 3764.0
If we subtract 168 from 178, we get 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:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 3764.2
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 8:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 3764.23
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.

Moving on to step 9:
If we divide 340 by 42, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 3764.238
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.

Advancing to step 10:
42 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 3764.238
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 3764.23809
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.

On to step 12:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3764.238095
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.

Let's proceed to step 13:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 3764.2380952
Deduct 84 from 100 and we're left 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.

Let's proceed to step 14:
160 divided by 42 is 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 3764.23809523
Subtracting 126 from 160 leaves us 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.

In conclusion, the division gives 3764.23809523 with a balance of 3.4e-08.
