We're dividing 66942835 by 839 
We want to figure out the number of times 66942835 can be divided by 839.

Going ahead to step 1:
839 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 839

Advancing to step 2:
If we divide 66 by 839, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 839

Let's proceed to step 3:
The number 839 fits into 669 0 times, leaving a remainder of 669.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 669 to get 669.
Grab the next digit (4) from the dividend, add it to 669, then carry on: 6694 / 839

Step 4:
839 goes into 6694 7 times with a remainder of 821.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 5873 from 6694 leaves us with 821.
Grab the next digit (2) from the dividend, add it to 821, then carry on: 8212 / 839

On to step 5:
839 goes into 8212 9 times with a remainder of 661.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we subtract 7551 from 8212, we get 661.
Take the next digit (8) from the dividend and append it to 661, then repeat: 6618 / 839

On to step 6:
839 can be fit into 6618 7 times, resulting in a remainder of 745.
Write down 7 as next digit of the result. 
Result so far: 797.0
Deduct 5873 from 6618 and we're left with 745.
Grab the next digit (3) from the dividend, add it to 745, then carry on: 7453 / 839

Advancing to step 7:
839 goes into 7453 8 times with a remainder of 741.
Put 8 as the next digit of the answer. 
Result so far: 7978.0
Deduct 6712 from 7453 and we're left with 741.
Fetch the next digit (5) from the dividend, attach it to 741 and continue: 7415 / 839

Moving on to step 8:
When dividing 7415 by 839, we get 8 with a remainder of 703.
Use 8 as the next digit of our solution. 
Result so far: 79788.0
The remainder is 703 after subtracting 6712 from 7415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Moving on to step 9:
7030 divided by 839 is 8 with a remainder of 318.
Record the quotient 8 as the next digit in the result. 
Result so far: 79788.8
The remainder is 318 after subtracting 6712 from 7030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 10:
3180 divided by 839 is 3 with a remainder of 663.
The next digit of our result is 3. 
Result so far: 79788.83
Subtracting 2517 from 3180 leaves us with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Let's proceed to step 11:
If we divide 6630 by 839, we get 7 and a remainder of 757.
The number 7 becomes the next digit in our result. 
Result so far: 79788.837
Subtracting 5873 from 6630 leaves us with 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Step 12:
839 goes into 7570 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 79788.8379
If we take 7551 away from 7570, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
The number 839 fits into 190 0 times, leaving a remainder of 190.
The next digit of our result is 0. 
Result so far: 79788.8379
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 14:
If we divide 1900 by 839, we get 2 and a remainder of 222.
Record the quotient 2 as the next digit in the result. 
Result so far: 79788.837902
Subtract 1678 from 1900 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 15:
The number 839 fits into 2220 2 times, leaving a remainder of 542.
The number 2 becomes the next digit in our result. 
Result so far: 79788.8379022
The remainder is 542 after subtracting 1678 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

The quotient of the division is 79788.8379022, and the remainder is 5.42e-06.
