Let's divide 655987 by 42
We want to divide 655987 by 42.

Step 1:
If we divide 6 by 42, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 42

On to step 2:
42 goes into 65 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 42 away from 65, we end up with 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 42

Step 3:
42 can be fit into 235 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 210 from 235 leaves us with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 42

Step 4:
When dividing 259 by 42, we get 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
Deduct 252 from 259 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 42

Step 5:
42 can be fit into 78 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1561.0
If we take 42 away from 78, we end up with 36.
Fetch the next digit (7) from the dividend, attach it to 36 and continue: 367 / 42

Let's proceed to step 6:
42 can be fit into 367 8 times, resulting in a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 15618.0
If we subtract 336 from 367, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
The number 42 fits into 310 7 times, leaving a remainder of 16.
The next digit of our result is 7. 
Result so far: 15618.7
If we subtract 294 from 310, 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.

Step 8:
42 goes into 160 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 15618.73
Deduct 126 from 160 and we're left 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.

Step 9:
42 goes into 340 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 15618.738
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.

On to step 10:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 15618.738
Subtracting 0 from 40 leaves us 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.

Advancing to step 11:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 15618.73809
Subtracting 378 from 400 leaves us 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.

Advancing to step 12:
220 divided by 42 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15618.738095
Subtract 210 from 220 to 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 13:
100 divided by 42 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 15618.7380952
If we take 84 away from 100, we end up 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:
If we divide 160 by 42, we get 3 and a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 15618.73809523
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.

The final outcome is 15618.73809523, with a leftover of 3.4e-08.
