191594 ÷ 42 
Let's see how many times 42 fits into 191594.

Going ahead to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 42

On to step 2:
The number 42 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 42

Let's proceed to step 3:
The number 42 fits into 191 4 times, leaving a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 168 from 191, we get 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 42

Let's proceed to step 4:
If we divide 235 by 42, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 25 after subtracting 210 from 235.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 42

Step 5:
When dividing 259 by 42, we get 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 456.0
If we take 252 away from 259, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 42

Advancing to step 6:
When dividing 74 by 42, we get 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 4561.0
Deduct 42 from 74 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
42 goes into 320 7 times with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 4561.7
Deduct 294 from 320 and we're left 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.

Going ahead to step 8:
If we divide 260 by 42, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 4561.76
If we take 252 away from 260, we end up with 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 9:
80 divided by 42 is 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 4561.761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
When dividing 380 by 42, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 4561.7619
Subtracting 378 from 380 leaves us 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 11:
The number 42 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 4561.7619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
42 goes into 200 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 4561.761904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
42 goes into 320 7 times with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 4561.7619047
Subtracting 294 from 320 leaves us 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.

Advancing to step 14:
If we divide 260 by 42, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 4561.76190476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 4561.76190476 with a balance of 8e-09.
