We look at the division of 18171210 by 395 
We want to divide 18171210 by 395.

Moving on to step 1:
When dividing 1 by 395, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 395

Step 2:
When dividing 18 by 395, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 395

Moving on to step 3:
The number 395 fits into 181 0 times, leaving a remainder of 181.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 181 to get 181.
Append the next digit (7) from the dividend to 181 and continue with: 1817 / 395

Advancing to step 4:
395 goes into 1817 4 times with a remainder of 237.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1580 from 1817 to get 237.
Grab the next digit (1) from the dividend, add it to 237, then carry on: 2371 / 395

Moving on to step 5:
2371 divided by 395 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtract 2370 from 2371 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 395

Step 6:
When dividing 12 by 395, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 460.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 395

Advancing to step 7:
395 can be fit into 121 0 times, resulting in a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 4600.0
The remainder is 121 after subtracting 0 from 121.
Include the next digit (0) from the dividend after 121, then repeat: 1210 / 395

Step 8:
The number 395 fits into 1210 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 46003.0
If we take 1185 away from 1210, we end up 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.

Going ahead to step 9:
395 can be fit into 250 0 times, resulting in a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 46003.0
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
If we divide 2500 by 395, we get 6 and a remainder of 130.
The number 6 becomes the next digit in our result. 
Result so far: 46003.06
If we take 2370 away from 2500, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 11:
395 can be fit into 1300 3 times, resulting in a remainder of 115.
The number 3 becomes the next digit in our result. 
Result so far: 46003.063
Subtracting 1185 from 1300 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 12:
The number 395 fits into 1150 2 times, leaving a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 46003.0632
If we subtract 790 from 1150, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 13:
395 can be fit into 3600 9 times, resulting in a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 46003.06329
Deduct 3555 from 3600 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 14:
450 divided by 395 is 1 with a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 46003.063291
Deduct 395 from 450 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 15:
When dividing 550 by 395, we get 1 with a remainder of 155.
Record the quotient 1 as the next digit in the result. 
Result so far: 46003.0632911
Subtracting 395 from 550 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

After the division, we end up with 46003.0632911 and a remainder of 1.55e-06.
