Let's divide 81941926 by 398
We want to divide 81941926 by 398.

Going ahead to step 1:
If we divide 8 by 398, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 398

Let's proceed to step 2:
The number 398 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 398

Advancing to step 3:
398 can be fit into 819 2 times, resulting in a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 796 from 819 leaves us with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 398

Advancing to step 4:
The number 398 fits into 234 0 times, leaving a remainder of 234.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 234 and we're left with 234.
Fetch the next digit (1) from the dividend, attach it to 234 and continue: 2341 / 398

Moving on to step 5:
398 goes into 2341 5 times with a remainder of 351.
Put 5 as the next digit of the answer. 
Result so far: 205.0
If we take 1990 away from 2341, we end up with 351.
Grab the next digit (9) from the dividend, add it to 351, then carry on: 3519 / 398

Advancing to step 6:
The number 398 fits into 3519 8 times, leaving a remainder of 335.
The next digit of our result is 8. 
Result so far: 2058.0
If we take 3184 away from 3519, we end up with 335.
Append the next digit (2) from the dividend to 335 and continue with: 3352 / 398

Going ahead to step 7:
When dividing 3352 by 398, we get 8 with a remainder of 168.
Use 8 as the next digit of our solution. 
Result so far: 20588.0
Deduct 3184 from 3352 and we're left with 168.
Take the next digit (6) from the dividend and append it to 168, then repeat: 1686 / 398

Going ahead to step 8:
When dividing 1686 by 398, we get 4 with a remainder of 94.
The next digit of our result is 4. 
Result so far: 205884.0
Subtract 1592 from 1686 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 9:
The number 398 fits into 940 2 times, leaving a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 205884.2
The remainder is 144 after subtracting 796 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 10:
398 can be fit into 1440 3 times, resulting in a remainder of 246.
The number 3 becomes the next digit in our result. 
Result so far: 205884.23
Deduct 1194 from 1440 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 11:
398 goes into 2460 6 times with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 205884.236
If we subtract 2388 from 2460, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
When dividing 720 by 398, we get 1 with a remainder of 322.
Use 1 as the next digit of our solution. 
Result so far: 205884.2361
The remainder is 322 after subtracting 398 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 13:
The number 398 fits into 3220 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 205884.23618
Subtracting 3184 from 3220 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
When dividing 360 by 398, we get 0 with a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 205884.23618
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 15:
If we divide 3600 by 398, we get 9 and a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 205884.2361809
Subtracting 3582 from 3600 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 16:
When dividing 180 by 398, we get 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 205884.2361809
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 205884.2361809 with a remaining 1.8e-07.
