We look at the division of 39853112 by 615 
We want to figure out the number of times 39853112 can be divided by 615.

Going ahead to step 1:
3 divided by 615 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 615

On to step 2:
39 divided by 615 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 615

Moving on to step 3:
When dividing 398 by 615, we get 0 with a remainder of 398.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 398, we get 398.
Include the next digit (5) from the dividend after 398, then repeat: 3985 / 615

Advancing to step 4:
The number 615 fits into 3985 6 times, leaving a remainder of 295.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 3690 from 3985 and we're left with 295.
Bring next digit (3) of the dividend behind the 295 and repeat the process: 2953 / 615

Going ahead to step 5:
615 can be fit into 2953 4 times, resulting in a remainder of 493.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we subtract 2460 from 2953, we get 493.
Take the next digit (1) from the dividend and append it to 493, then repeat: 4931 / 615

Advancing to step 6:
615 goes into 4931 8 times with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 648.0
If we subtract 4920 from 4931, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 615

On to step 7:
111 divided by 615 is 0 with a remainder of 111.
Put 0 as the next digit of the answer. 
Result so far: 6480.0
Subtract 0 from 111 to get 111.
Fetch the next digit (2) from the dividend, attach it to 111 and continue: 1112 / 615

Advancing to step 8:
If we divide 1112 by 615, we get 1 and a remainder of 497.
Record the quotient 1 as the next digit in the result. 
Result so far: 64801.0
Deduct 615 from 1112 and we're left with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Advancing to step 9:
The number 615 fits into 4970 8 times, leaving a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 64801.8
The remainder is 50 after subtracting 4920 from 4970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 615, we get 0 and a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 64801.8
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 11:
If we divide 5000 by 615, we get 8 and a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 64801.808
Subtract 4920 from 5000 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
615 can be fit into 800 1 times, resulting in a remainder of 185.
Record the quotient 1 as the next digit in the result. 
Result so far: 64801.8081
Subtracting 615 from 800 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 13:
615 can be fit into 1850 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 64801.80813
Subtracting 1845 from 1850 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
615 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 64801.80813
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 15:
When dividing 500 by 615, we get 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 64801.80813
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 64801.80813 with a remaining 5e-06.
