We look at the division of 68166150 by 398 
We're looking to find how many times 398 goes into 68166150.

Advancing to step 1:
If we divide 6 by 398, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 398

Going ahead to step 2:
When dividing 68 by 398, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 398

Let's proceed to step 3:
681 divided by 398 is 1 with a remainder of 283.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 398 from 681 and we're left with 283.
Fetch the next digit (6) from the dividend, attach it to 283 and continue: 2836 / 398

On to step 4:
The number 398 fits into 2836 7 times, leaving a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 2786 away from 2836, we end up with 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 398

Going ahead to step 5:
The number 398 fits into 506 1 times, leaving a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 171.0
Subtracting 398 from 506 leaves us with 108.
Include the next digit (1) from the dividend after 108, then repeat: 1081 / 398

Moving on to step 6:
If we divide 1081 by 398, we get 2 and a remainder of 285.
The next digit of our result is 2. 
Result so far: 1712.0
The remainder is 285 after subtracting 796 from 1081.
Fetch the next digit (5) from the dividend, attach it to 285 and continue: 2855 / 398

On to step 7:
If we divide 2855 by 398, we get 7 and a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 17127.0
If we subtract 2786 from 2855, we get 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 398

Let's proceed to step 8:
The number 398 fits into 690 1 times, leaving a remainder of 292.
Record the quotient 1 as the next digit in the result. 
Result so far: 171271.0
If we subtract 398 from 690, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 9:
2920 divided by 398 is 7 with a remainder of 134.
Record the quotient 7 as the next digit in the result. 
Result so far: 171271.7
If we take 2786 away from 2920, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 10:
398 goes into 1340 3 times with a remainder of 146.
Write down 3 as next digit of the result. 
Result so far: 171271.73
If we subtract 1194 from 1340, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 11:
When dividing 1460 by 398, we get 3 with a remainder of 266.
Use 3 as the next digit of our solution. 
Result so far: 171271.733
The remainder is 266 after subtracting 1194 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The quotient of the division is 171271.733, and the remainder is 0.0266.
