We look at the division of 1397765 by 415 
Let's see how many times 415 fits into 1397765.

Step 1:
1 divided by 415 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 415

On to step 2:
415 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 415

On to step 3:
When dividing 139 by 415, we get 0 with a remainder of 139.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 139 after subtracting 0 from 139.
Take the next digit (7) from the dividend and append it to 139, then repeat: 1397 / 415

Going ahead to step 4:
If we divide 1397 by 415, we get 3 and a remainder of 152.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 1245 from 1397 to get 152.
Grab the next digit (7) from the dividend, add it to 152, then carry on: 1527 / 415

Moving on to step 5:
415 can be fit into 1527 3 times, resulting in a remainder of 282.
Put 3 as the next digit of the answer. 
Result so far: 33.0
The remainder is 282 after subtracting 1245 from 1527.
Append the next digit (6) from the dividend to 282 and continue with: 2826 / 415

On to step 6:
When dividing 2826 by 415, we get 6 with a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 336.0
If we take 2490 away from 2826, we end up with 336.
Append the next digit (5) from the dividend to 336 and continue with: 3365 / 415

Moving on to step 7:
If we divide 3365 by 415, we get 8 and a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 3368.0
If we subtract 3320 from 3365, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
415 can be fit into 450 1 times, resulting in a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 3368.1
Deduct 415 from 450 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
When dividing 350 by 415, we get 0 with a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 3368.1
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
3500 divided by 415 is 8 with a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 3368.108
Deduct 3320 from 3500 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
415 goes into 1800 4 times with a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 3368.1084
Deduct 1660 from 1800 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
When dividing 1400 by 415, we get 3 with a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 3368.10843
Subtract 1245 from 1400 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 13:
The number 415 fits into 1550 3 times, leaving a remainder of 305.
The next digit of our result is 3. 
Result so far: 3368.108433
Deduct 1245 from 1550 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

The final result is 3368.108433 with a remainder of 3.05e-05.
