We're dividing 70644378 by 721 
We want to figure out the number of times 70644378 can be divided by 721.

Let's proceed to step 1:
When dividing 7 by 721, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 721

Advancing to step 2:
721 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (6) from the dividend, attach it to 70 and continue: 706 / 721

Going ahead to step 3:
721 goes into 706 0 times with a remainder of 706.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 706 after subtracting 0 from 706.
Grab the next digit (4) from the dividend, add it to 706, then carry on: 7064 / 721

Let's proceed to step 4:
721 goes into 7064 9 times with a remainder of 575.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 6489 from 7064 to get 575.
Take the next digit (4) from the dividend and append it to 575, then repeat: 5754 / 721

Going ahead to step 5:
If we divide 5754 by 721, we get 7 and a remainder of 707.
The next digit of our result is 7. 
Result so far: 97.0
If we take 5047 away from 5754, we end up with 707.
Bring next digit (3) of the dividend behind the 707 and repeat the process: 7073 / 721

Step 6:
721 can be fit into 7073 9 times, resulting in a remainder of 584.
The number 9 becomes the next digit in our result. 
Result so far: 979.0
Subtract 6489 from 7073 to get 584.
Bring next digit (7) of the dividend behind the 584 and repeat the process: 5847 / 721

Step 7:
5847 divided by 721 is 8 with a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 9798.0
Subtract 5768 from 5847 to get 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 721

Let's proceed to step 8:
721 goes into 798 1 times with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 97981.0
The remainder is 77 after subtracting 721 from 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
770 divided by 721 is 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 97981.1
Subtracting 721 from 770 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 10:
When dividing 490 by 721, we get 0 with a remainder of 490.
Write down 0 as next digit of the result. 
Result so far: 97981.1
Deduct 0 from 490 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 11:
4900 divided by 721 is 6 with a remainder of 574.
The next digit of our result is 6. 
Result so far: 97981.106
Subtracting 4326 from 4900 leaves us with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Advancing to step 12:
If we divide 5740 by 721, we get 7 and a remainder of 693.
Put 7 as the next digit of the answer. 
Result so far: 97981.1067
Deduct 5047 from 5740 and we're left with 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

On to step 13:
If we divide 6930 by 721, we get 9 and a remainder of 441.
Put 9 as the next digit of the answer. 
Result so far: 97981.10679
Deduct 6489 from 6930 and we're left with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Advancing to step 14:
When dividing 4410 by 721, we get 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 97981.106796
The remainder is 84 after subtracting 4326 from 4410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 15:
The number 721 fits into 840 1 times, leaving a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 97981.1067961
If we take 721 away from 840, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 16:
721 goes into 1190 1 times with a remainder of 469.
The number 1 becomes the next digit in our result. 
Result so far: 97981.10679611
Subtracting 721 from 1190 leaves us with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

After the division, we end up with 97981.10679611 and a remainder of 4.69e-07.
