We divide 7042821 by 721
We're looking to find how many times 721 goes into 7042821.

Advancing to step 1:
When dividing 7 by 721, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 721

Advancing to step 2:
721 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 721

On to step 3:
721 can be fit into 704 0 times, resulting in a remainder of 704.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 704 leaves us with 704.
Take the next digit (2) from the dividend and append it to 704, then repeat: 7042 / 721

Let's proceed to step 4:
721 goes into 7042 9 times with a remainder of 553.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 6489 from 7042, we get 553.
Bring next digit (8) of the dividend behind the 553 and repeat the process: 5538 / 721

Going ahead to step 5:
721 goes into 5538 7 times with a remainder of 491.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we take 5047 away from 5538, we end up with 491.
Take the next digit (2) from the dividend and append it to 491, then repeat: 4912 / 721

On to step 6:
4912 divided by 721 is 6 with a remainder of 586.
Use 6 as the next digit of our solution. 
Result so far: 976.0
If we take 4326 away from 4912, we end up with 586.
Fetch the next digit (1) from the dividend, attach it to 586 and continue: 5861 / 721

Step 7:
When dividing 5861 by 721, we get 8 with a remainder of 93.
Use 8 as the next digit of our solution. 
Result so far: 9768.0
If we subtract 5768 from 5861, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 8:
When dividing 930 by 721, we get 1 with a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 9768.1
Subtracting 721 from 930 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 9:
If we divide 2090 by 721, we get 2 and a remainder of 648.
Record the quotient 2 as the next digit in the result. 
Result so far: 9768.12
The remainder is 648 after subtracting 1442 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Moving on to step 10:
721 can be fit into 6480 8 times, resulting in a remainder of 712.
Write down 8 as next digit of the result. 
Result so far: 9768.128
If we subtract 5768 from 6480, we get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Let's proceed to step 11:
The number 721 fits into 7120 9 times, leaving a remainder of 631.
Record the quotient 9 as the next digit in the result. 
Result so far: 9768.1289
If we take 6489 away from 7120, we end up with 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Step 12:
If we divide 6310 by 721, we get 8 and a remainder of 542.
Put 8 as the next digit of the answer. 
Result so far: 9768.12898
If we subtract 5768 from 6310, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 13:
5420 divided by 721 is 7 with a remainder of 373.
Use 7 as the next digit of our solution. 
Result so far: 9768.128987
Deduct 5047 from 5420 and we're left with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 14:
721 goes into 3730 5 times with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 9768.1289875
Subtract 3605 from 3730 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 15:
721 goes into 1250 1 times with a remainder of 529.
Use 1 as the next digit of our solution. 
Result so far: 9768.12898751
If we subtract 721 from 1250, we get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

The final outcome is 9768.12898751, with a leftover of 5.29e-07.
