Let's divide 843947 by 42
We want to figure out the number of times 843947 can be divided by 42.

Advancing to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 42

Step 2:
42 goes into 84 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 84 from 84, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 42

Advancing to step 3:
The number 42 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 42

On to step 4:
42 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 200.0
Subtract 0 from 39 to get 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 42

On to step 5:
The number 42 fits into 394 9 times, leaving a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 2009.0
If we subtract 378 from 394, we get 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 42

Going ahead to step 6:
167 divided by 42 is 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 20093.0
If we take 126 away from 167, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
The number 42 fits into 410 9 times, leaving a remainder of 32.
The next digit of our result is 9. 
Result so far: 20093.9
Subtracting 378 from 410 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
When dividing 320 by 42, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 20093.97
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
The number 42 fits into 260 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 20093.976
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
When dividing 80 by 42, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 20093.9761
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
42 goes into 380 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 20093.97619
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
When dividing 20 by 42, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 20093.97619
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
If we divide 200 by 42, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 20093.9761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
320 divided by 42 is 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 20093.97619047
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 20093.97619047, and the remainder is 2.6e-08.
