We look at the division of 18118591 by 39 
Our goal is to divide 18118591 by 39.

Going ahead to step 1:
39 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 39

Let's proceed to step 2:
When dividing 18 by 39, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 39

Let's proceed to step 3:
If we divide 181 by 39, we get 4 and a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 25 after subtracting 156 from 181.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 39

Let's proceed to step 4:
The number 39 fits into 251 6 times, leaving a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Deduct 234 from 251 and we're left with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 39

Advancing to step 5:
When dividing 178 by 39, we get 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 464.0
Deduct 156 from 178 and we're left with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 39

Let's proceed to step 6:
When dividing 225 by 39, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 4645.0
Subtract 195 from 225 to get 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 39

Step 7:
When dividing 309 by 39, we get 7 with a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 46457.0
If we subtract 273 from 309, we get 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 39

Advancing to step 8:
361 divided by 39 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 464579.0
Subtract 351 from 361 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 464579.2
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
The number 39 fits into 220 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 464579.25
Subtracting 195 from 220 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
The number 39 fits into 250 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 464579.256
If we take 234 away from 250, we end up 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.

Step 12:
160 divided by 39 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 464579.2564
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
39 goes into 40 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 464579.25641
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
10 divided by 39 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 464579.25641
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 15:
100 divided by 39 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 464579.2564102
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 16:
39 goes into 220 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 464579.25641025
Subtracting 195 from 220 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 464579.25641025, and the remainder is 2.5e-08.
