40086625 ÷ 721 
Let's see how many times 721 fits into 40086625.

On to step 1:
721 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 721

Let's proceed to step 2:
721 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 721

Step 3:
721 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 400 and we're left with 400.
Take the next digit (8) from the dividend and append it to 400, then repeat: 4008 / 721

Moving on to step 4:
When dividing 4008 by 721, we get 5 with a remainder of 403.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 3605 away from 4008, we end up with 403.
Bring next digit (6) of the dividend behind the 403 and repeat the process: 4036 / 721

Advancing to step 5:
721 goes into 4036 5 times with a remainder of 431.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Deduct 3605 from 4036 and we're left with 431.
Take the next digit (6) from the dividend and append it to 431, then repeat: 4316 / 721

Advancing to step 6:
721 can be fit into 4316 5 times, resulting in a remainder of 711.
Record the quotient 5 as the next digit in the result. 
Result so far: 555.0
If we subtract 3605 from 4316, we get 711.
Take the next digit (2) from the dividend and append it to 711, then repeat: 7112 / 721

Let's proceed to step 7:
7112 divided by 721 is 9 with a remainder of 623.
The next digit of our result is 9. 
Result so far: 5559.0
Subtract 6489 from 7112 to get 623.
Include the next digit (5) from the dividend after 623, then repeat: 6235 / 721

Moving on to step 8:
6235 divided by 721 is 8 with a remainder of 467.
The next digit of our result is 8. 
Result so far: 55598.0
Subtracting 5768 from 6235 leaves us with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Going ahead to step 9:
721 can be fit into 4670 6 times, resulting in a remainder of 344.
Write down 6 as next digit of the result. 
Result so far: 55598.6
If we subtract 4326 from 4670, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 10:
The number 721 fits into 3440 4 times, leaving a remainder of 556.
Use 4 as the next digit of our solution. 
Result so far: 55598.64
If we subtract 2884 from 3440, we get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Let's proceed to step 11:
The number 721 fits into 5560 7 times, leaving a remainder of 513.
Record the quotient 7 as the next digit in the result. 
Result so far: 55598.647
If we take 5047 away from 5560, we end up with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Advancing to step 12:
If we divide 5130 by 721, we get 7 and a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 55598.6477
If we subtract 5047 from 5130, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The quotient of the division is 55598.6477, and the remainder is 0.00083.
