3418781 ÷ 398 
Our goal is to divide 3418781 by 398.

Moving on to step 1:
The number 398 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 398

Going ahead to step 2:
398 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 398

Moving on to step 3:
If we divide 341 by 398, we get 0 and a remainder of 341.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 341 leaves us with 341.
Bring next digit (8) of the dividend behind the 341 and repeat the process: 3418 / 398

Going ahead to step 4:
398 can be fit into 3418 8 times, resulting in a remainder of 234.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 3184 from 3418 and we're left with 234.
Bring next digit (7) of the dividend behind the 234 and repeat the process: 2347 / 398

Step 5:
398 goes into 2347 5 times with a remainder of 357.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtract 1990 from 2347 to get 357.
Take the next digit (8) from the dividend and append it to 357, then repeat: 3578 / 398

Step 6:
When dividing 3578 by 398, we get 8 with a remainder of 394.
Use 8 as the next digit of our solution. 
Result so far: 858.0
The remainder is 394 after subtracting 3184 from 3578.
Append the next digit (1) from the dividend to 394 and continue with: 3941 / 398

Step 7:
If we divide 3941 by 398, we get 9 and a remainder of 359.
Use 9 as the next digit of our solution. 
Result so far: 8589.0
Deduct 3582 from 3941 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 8:
3590 divided by 398 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 8589.9
The remainder is 8 after subtracting 3582 from 3590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
The number 398 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 8589.9
If we take 0 away from 80, we end up with 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 10:
398 goes into 800 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 8589.902
Deduct 796 from 800 and we're left 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.

Let's proceed to step 11:
The number 398 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8589.902
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
398 can be fit into 400 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 8589.90201
Subtracting 398 from 400 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
The number 398 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8589.90201
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
If we divide 200 by 398, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 8589.90201
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 8589.90201 with a balance of 2e-06.
