We look at the division of 14875579 by 721 
We're looking to find how many times 721 goes into 14875579.

On to step 1:
If we divide 1 by 721, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 721

Advancing to step 2:
The number 721 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 721

Moving on to step 3:
When dividing 148 by 721, we get 0 with a remainder of 148.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 148 leaves us with 148.
Grab the next digit (7) from the dividend, add it to 148, then carry on: 1487 / 721

Moving on to step 4:
1487 divided by 721 is 2 with a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1442 away from 1487, we end up with 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 721

On to step 5:
When dividing 455 by 721, we get 0 with a remainder of 455.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 455 leaves us with 455.
Bring next digit (5) of the dividend behind the 455 and repeat the process: 4555 / 721

Let's proceed to step 6:
4555 divided by 721 is 6 with a remainder of 229.
The next digit of our result is 6. 
Result so far: 206.0
Deduct 4326 from 4555 and we're left with 229.
Take the next digit (7) from the dividend and append it to 229, then repeat: 2297 / 721

On to step 7:
When dividing 2297 by 721, we get 3 with a remainder of 134.
The next digit of our result is 3. 
Result so far: 2063.0
Subtracting 2163 from 2297 leaves us with 134.
Bring next digit (9) of the dividend behind the 134 and repeat the process: 1349 / 721

Moving on to step 8:
721 can be fit into 1349 1 times, resulting in a remainder of 628.
The next digit of our result is 1. 
Result so far: 20631.0
If we take 721 away from 1349, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

On to step 9:
6280 divided by 721 is 8 with a remainder of 512.
Record the quotient 8 as the next digit in the result. 
Result so far: 20631.8
If we subtract 5768 from 6280, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 10:
721 can be fit into 5120 7 times, resulting in a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 20631.87
Subtracting 5047 from 5120 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 11:
730 divided by 721 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 20631.871
If we take 721 away from 730, we end up 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 12:
721 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 20631.871
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 13:
900 divided by 721 is 1 with a remainder of 179.
The number 1 becomes the next digit in our result. 
Result so far: 20631.87101
If we subtract 721 from 900, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 14:
When dividing 1790 by 721, we get 2 with a remainder of 348.
Use 2 as the next digit of our solution. 
Result so far: 20631.871012
Subtract 1442 from 1790 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 15:
3480 divided by 721 is 4 with a remainder of 596.
Put 4 as the next digit of the answer. 
Result so far: 20631.8710124
Deduct 2884 from 3480 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 16:
If we divide 5960 by 721, we get 8 and a remainder of 192.
Record the quotient 8 as the next digit in the result. 
Result so far: 20631.87101248
If we take 5768 away from 5960, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The quotient of the division is 20631.87101248, and the remainder is 1.92e-07.
