We look at the division of 39891301 by 72 
Let's see how many times 72 fits into 39891301.

Let's proceed to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 72

Advancing to step 2:
39 divided by 72 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 72

Moving on to step 3:
398 divided by 72 is 5 with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 360 from 398, we get 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 72

Let's proceed to step 4:
72 can be fit into 389 5 times, resulting in a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Subtracting 360 from 389 leaves us with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 72

Advancing to step 5:
291 divided by 72 is 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 554.0
Subtracting 288 from 291 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 72

On to step 6:
When dividing 33 by 72, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 5540.0
If we subtract 0 from 33, we get 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 72

Going ahead to step 7:
72 goes into 330 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 55404.0
The remainder is 42 after subtracting 288 from 330.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 72

Advancing to step 8:
When dividing 421 by 72, we get 5 with a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 554045.0
Subtracting 360 from 421 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
72 can be fit into 610 8 times, resulting in a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 554045.8
Subtract 576 from 610 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
The number 72 fits into 340 4 times, leaving a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 554045.84
The remainder is 52 after subtracting 288 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
72 goes into 520 7 times with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 554045.847
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
72 can be fit into 160 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 554045.8472
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 72, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 554045.84722
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 554045.84722, with a leftover of 1.6e-05.
