Let's divide 39672017 by 721
Let's see how many times 721 fits into 39672017.

Moving on to step 1:
When dividing 3 by 721, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 721

Moving on to step 2:
721 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 721

Step 3:
721 can be fit into 396 0 times, resulting in a remainder of 396.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 396 and we're left with 396.
Include the next digit (7) from the dividend after 396, then repeat: 3967 / 721

Let's proceed to step 4:
The number 721 fits into 3967 5 times, leaving a remainder of 362.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 3605 from 3967 and we're left with 362.
Take the next digit (2) from the dividend and append it to 362, then repeat: 3622 / 721

Advancing to step 5:
721 goes into 3622 5 times with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtracting 3605 from 3622 leaves us with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 721

Advancing to step 6:
If we divide 170 by 721, we get 0 and a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 550.0
Deduct 0 from 170 and we're left with 170.
Bring next digit (1) of the dividend behind the 170 and repeat the process: 1701 / 721

On to step 7:
The number 721 fits into 1701 2 times, leaving a remainder of 259.
Put 2 as the next digit of the answer. 
Result so far: 5502.0
Deduct 1442 from 1701 and we're left with 259.
Take the next digit (7) from the dividend and append it to 259, then repeat: 2597 / 721

Moving on to step 8:
The number 721 fits into 2597 3 times, leaving a remainder of 434.
The next digit of our result is 3. 
Result so far: 55023.0
If we subtract 2163 from 2597, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Going ahead to step 9:
4340 divided by 721 is 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 55023.6
If we take 4326 away from 4340, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
140 divided by 721 is 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 55023.6
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
721 can be fit into 1400 1 times, resulting in a remainder of 679.
Use 1 as the next digit of our solution. 
Result so far: 55023.601
If we subtract 721 from 1400, we get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Moving on to step 12:
The number 721 fits into 6790 9 times, leaving a remainder of 301.
Record the quotient 9 as the next digit in the result. 
Result so far: 55023.6019
Subtract 6489 from 6790 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 13:
If we divide 3010 by 721, we get 4 and a remainder of 126.
Use 4 as the next digit of our solution. 
Result so far: 55023.60194
If we take 2884 away from 3010, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 14:
721 goes into 1260 1 times with a remainder of 539.
Record the quotient 1 as the next digit in the result. 
Result so far: 55023.601941
The remainder is 539 after subtracting 721 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Let's proceed to step 15:
721 goes into 5390 7 times with a remainder of 343.
The number 7 becomes the next digit in our result. 
Result so far: 55023.6019417
Subtract 5047 from 5390 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Advancing to step 16:
When dividing 3430 by 721, we get 4 with a remainder of 546.
The number 4 becomes the next digit in our result. 
Result so far: 55023.60194174
If we take 2884 away from 3430, we end up with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

The final outcome is 55023.60194174, with a leftover of 5.46e-07.
