We look at the division of 842806 by 721 
We want to figure out the number of times 842806 can be divided by 721.

Advancing to step 1:
8 divided by 721 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 721

Moving on to step 2:
If we divide 84 by 721, we get 0 and a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Take the next digit (2) from the dividend and append it to 84, then repeat: 842 / 721

Moving on to step 3:
842 divided by 721 is 1 with a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 121 after subtracting 721 from 842.
Append the next digit (8) from the dividend to 121 and continue with: 1218 / 721

Step 4:
The number 721 fits into 1218 1 times, leaving a remainder of 497.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 721 from 1218 and we're left with 497.
Take the next digit (0) from the dividend and append it to 497, then repeat: 4970 / 721

Moving on to step 5:
4970 divided by 721 is 6 with a remainder of 644.
The next digit of our result is 6. 
Result so far: 116.0
If we subtract 4326 from 4970, we get 644.
Include the next digit (6) from the dividend after 644, then repeat: 6446 / 721

On to step 6:
The number 721 fits into 6446 8 times, leaving a remainder of 678.
Put 8 as the next digit of the answer. 
Result so far: 1168.0
The remainder is 678 after subtracting 5768 from 6446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Going ahead to step 7:
The number 721 fits into 6780 9 times, leaving a remainder of 291.
Write down 9 as next digit of the result. 
Result so far: 1168.9
Subtract 6489 from 6780 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 8:
When dividing 2910 by 721, we get 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 1168.94
Deduct 2884 from 2910 and we're left 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.

Let's proceed to step 9:
721 can be fit into 260 0 times, resulting in a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 1168.94
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
721 goes into 2600 3 times with a remainder of 437.
The next digit of our result is 3. 
Result so far: 1168.9403
Subtracting 2163 from 2600 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Step 11:
The number 721 fits into 4370 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 1168.94036
Subtracting 4326 from 4370 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
When dividing 440 by 721, we get 0 with a remainder of 440.
The next digit of our result is 0. 
Result so far: 1168.94036
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 13:
When dividing 4400 by 721, we get 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 1168.9403606
Subtract 4326 from 4400 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 14:
740 divided by 721 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1168.94036061
If we take 721 away from 740, 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.

The final outcome is 1168.94036061, with a leftover of 1.9e-08.
