We look at the division of 700842 by 21 
We want to figure out the number of times 700842 can be divided by 21.

Let's proceed to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 21

Advancing to step 2:
21 goes into 70 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 63 from 70, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 21

Moving on to step 3:
21 can be fit into 70 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
The remainder is 7 after subtracting 63 from 70.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 21

Step 4:
The number 21 fits into 78 3 times, leaving a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 333.0
Deduct 63 from 78 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 21

Going ahead to step 5:
21 goes into 154 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 3337.0
If we subtract 147 from 154, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 21

Going ahead to step 6:
The number 21 fits into 72 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 33373.0
Deduct 63 from 72 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
21 goes into 90 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 33373.4
If we subtract 84 from 90, 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.

Let's proceed to step 8:
21 goes into 60 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 33373.42
Deduct 42 from 60 and we're left 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 9:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 33373.428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 33373.4285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
When dividing 150 by 21, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 33373.42857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 33373.428571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
90 divided by 21 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 33373.4285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
21 goes into 60 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 33373.42857142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 33373.42857142 with a balance of 1.8e-08.
