591544 ÷ 42 
We're looking to find how many times 42 goes into 591544.

On to step 1:
The number 42 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 42

Going ahead to step 2:
The number 42 fits into 59 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 42 from 59 leaves us with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 42

Step 3:
When dividing 171 by 42, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 168 from 171 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 42

On to step 4:
The number 42 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Subtract 0 from 35 to get 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 42

Advancing to step 5:
The number 42 fits into 354 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 1408.0
Subtract 336 from 354 to get 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 42

Going ahead to step 6:
If we divide 184 by 42, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 14084.0
Deduct 168 from 184 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.

Moving on to step 7:
When dividing 160 by 42, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 14084.3
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.

Step 8:
If we divide 340 by 42, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 14084.38
Deduct 336 from 340 and we're left 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.

Let's proceed to step 9:
When dividing 40 by 42, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 14084.38
If we subtract 0 from 40, we 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.

Advancing to step 10:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 14084.3809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
If we divide 220 by 42, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 14084.38095
If we subtract 210 from 220, 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.

Let's proceed to step 12:
42 goes into 100 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 14084.380952
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.

Going ahead to step 13:
If we divide 160 by 42, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 14084.3809523
If we take 126 away from 160, we end up 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 14:
If we divide 340 by 42, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 14084.38095238
If we take 336 away from 340, we end up 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.

The final result is 14084.38095238 with a remainder of 4e-09.
