We're dividing 81716438 by 398 
We want to figure out the number of times 81716438 can be divided by 398.

Going ahead to step 1:
8 divided by 398 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 398

Moving on to step 2:
398 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Grab the next digit (7) from the dividend, add it to 81, then carry on: 817 / 398

On to step 3:
If we divide 817 by 398, we get 2 and a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 796 from 817 to get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 398

Moving on to step 4:
398 goes into 211 0 times with a remainder of 211.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 211 to get 211.
Include the next digit (6) from the dividend after 211, then repeat: 2116 / 398

Going ahead to step 5:
When dividing 2116 by 398, we get 5 with a remainder of 126.
Put 5 as the next digit of the answer. 
Result so far: 205.0
If we subtract 1990 from 2116, we get 126.
Include the next digit (4) from the dividend after 126, then repeat: 1264 / 398

Let's proceed to step 6:
If we divide 1264 by 398, we get 3 and a remainder of 70.
The next digit of our result is 3. 
Result so far: 2053.0
If we take 1194 away from 1264, we end up with 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 398

On to step 7:
If we divide 703 by 398, we get 1 and a remainder of 305.
The number 1 becomes the next digit in our result. 
Result so far: 20531.0
Subtracting 398 from 703 leaves us with 305.
Take the next digit (8) from the dividend and append it to 305, then repeat: 3058 / 398

Moving on to step 8:
When dividing 3058 by 398, we get 7 with a remainder of 272.
The number 7 becomes the next digit in our result. 
Result so far: 205317.0
Deduct 2786 from 3058 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 9:
If we divide 2720 by 398, we get 6 and a remainder of 332.
Write down 6 as next digit of the result. 
Result so far: 205317.6
If we subtract 2388 from 2720, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 10:
398 can be fit into 3320 8 times, resulting in a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 205317.68
Subtracting 3184 from 3320 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 11:
398 goes into 1360 3 times with a remainder of 166.
The next digit of our result is 3. 
Result so far: 205317.683
The remainder is 166 after subtracting 1194 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 12:
398 can be fit into 1660 4 times, resulting in a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 205317.6834
Deduct 1592 from 1660 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 13:
When dividing 680 by 398, we get 1 with a remainder of 282.
Record the quotient 1 as the next digit in the result. 
Result so far: 205317.68341
Deduct 398 from 680 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 14:
When dividing 2820 by 398, we get 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 205317.683417
Subtracting 2786 from 2820 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 15:
340 divided by 398 is 0 with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 205317.683417
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 16:
When dividing 3400 by 398, we get 8 with a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 205317.68341708
Deduct 3184 from 3400 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 205317.68341708 and a remainder of 2.16e-07.
