We look at the division of 66347374 by 42 
We want to divide 66347374 by 42.

Moving on to step 1:
6 divided by 42 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 42

Going ahead to step 2:
If we divide 66 by 42, we get 1 and a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 42 from 66 to get 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 42

Let's proceed to step 3:
If we divide 243 by 42, we get 5 and a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 210 from 243, we get 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 42

Going ahead to step 4:
42 goes into 334 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Subtract 294 from 334 to get 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 42

On to step 5:
When dividing 407 by 42, we get 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 1579.0
If we take 378 away from 407, we end up with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 42

Step 6:
If we divide 293 by 42, we get 6 and a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 15796.0
The remainder is 41 after subtracting 252 from 293.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 42

Advancing to step 7:
42 goes into 417 9 times with a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 157969.0
Deduct 378 from 417 and we're left with 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 42

Going ahead to step 8:
394 divided by 42 is 9 with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 1579699.0
The remainder is 16 after subtracting 378 from 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
42 goes into 160 3 times with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 1579699.3
Subtract 126 from 160 to 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.

On to step 10:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 1579699.38
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.

Let's proceed to step 11:
42 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1579699.38
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.

Let's proceed to step 12:
If we divide 400 by 42, we get 9 and a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 1579699.3809
Deduct 378 from 400 and we're left 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.

Step 13:
When dividing 220 by 42, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 1579699.38095
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.

Step 14:
When dividing 100 by 42, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 1579699.380952
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.

Going ahead to step 15:
If we divide 160 by 42, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 1579699.3809523
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 16:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1579699.38095238
If we subtract 336 from 340, we 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.

The final result is 1579699.38095238 with a remainder of 4e-09.
