693594 divided by 42 
Let's see how many times 42 fits into 693594.

On to step 1:
The number 42 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 42

Moving on to step 2:
When dividing 69 by 42, we get 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 42 away from 69, we end up with 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 42

Moving on to step 3:
42 goes into 273 6 times with a remainder of 21.
The next digit of our result is 6. 
Result so far: 16.0
If we take 252 away from 273, we end up with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 42

On to step 4:
42 goes into 215 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 165.0
Deduct 210 from 215 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 42

Step 5:
59 divided by 42 is 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1651.0
Subtract 42 from 59 to get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 42

Going ahead to step 6:
The number 42 fits into 174 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 16514.0
If we subtract 168 from 174, we 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.

On to step 7:
60 divided by 42 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 16514.1
Subtracting 42 from 60 leaves us 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.

Going ahead to step 8:
42 goes into 180 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 16514.14
If we take 168 away from 180, we end up 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 9:
120 divided by 42 is 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 16514.142
If we take 84 away from 120, we end up 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 10:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 16514.1428
Deduct 336 from 360 and we're left 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.

Advancing to step 11:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 16514.14285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
300 divided by 42 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 16514.142857
Subtracting 294 from 300 leaves us 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.

Step 13:
42 goes into 60 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 16514.1428571
Subtracting 42 from 60 leaves us 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.

Advancing to step 14:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 16514.14285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 16514.14285714, with a leftover of 1.2e-08.
