We divide 72015808 by 39
We want to divide 72015808 by 39.

Step 1:
When dividing 7 by 39, 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.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 39

Moving on to step 2:
39 goes into 72 1 times with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 39 from 72 to get 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 39

Advancing to step 3:
The number 39 fits into 330 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 312 from 330 and we're left with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 39

On to step 4:
When dividing 181 by 39, we get 4 with a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 184.0
Subtract 156 from 181 to get 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 39

Let's proceed to step 5:
When dividing 255 by 39, we get 6 with a remainder of 21.
The next digit of our result is 6. 
Result so far: 1846.0
Deduct 234 from 255 and we're left with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 39

Step 6:
The number 39 fits into 218 5 times, leaving a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 18465.0
If we take 195 away from 218, we end up with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 39

Step 7:
The number 39 fits into 230 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 184655.0
If we take 195 away from 230, we end up with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 39

Let's proceed to step 8:
39 goes into 358 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 1846559.0
If we take 351 away from 358, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
When dividing 70 by 39, we get 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 1846559.1
Subtract 39 from 70 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 10:
310 divided by 39 is 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 1846559.17
If we take 273 away from 310, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
When dividing 370 by 39, we get 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 1846559.179
If we take 351 away from 370, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 12:
39 can be fit into 190 4 times, resulting in a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 1846559.1794
Deduct 156 from 190 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
39 goes into 340 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 1846559.17948
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
39 goes into 280 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 1846559.179487
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 15:
If we divide 70 by 39, we get 1 and a remainder of 31.
The next digit of our result is 1. 
Result so far: 1846559.1794871
The remainder is 31 after subtracting 39 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 16:
The number 39 fits into 310 7 times, leaving a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 1846559.17948717
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The quotient of the division is 1846559.17948717, and the remainder is 3.7e-08.
