Let's divide 67241986 by 398
We want to figure out the number of times 67241986 can be divided by 398.

Step 1:
398 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 398

Moving on to step 2:
67 divided by 398 is 0 with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 398

Moving on to step 3:
If we divide 672 by 398, we get 1 and a remainder of 274.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 398 from 672 leaves us with 274.
Grab the next digit (4) from the dividend, add it to 274, then carry on: 2744 / 398

Advancing to step 4:
The number 398 fits into 2744 6 times, leaving a remainder of 356.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 2388 from 2744 leaves us with 356.
Bring next digit (1) of the dividend behind the 356 and repeat the process: 3561 / 398

Advancing to step 5:
3561 divided by 398 is 8 with a remainder of 377.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
If we subtract 3184 from 3561, we get 377.
Take the next digit (9) from the dividend and append it to 377, then repeat: 3779 / 398

Let's proceed to step 6:
When dividing 3779 by 398, we get 9 with a remainder of 197.
Use 9 as the next digit of our solution. 
Result so far: 1689.0
Deduct 3582 from 3779 and we're left with 197.
Include the next digit (8) from the dividend after 197, then repeat: 1978 / 398

Let's proceed to step 7:
When dividing 1978 by 398, we get 4 with a remainder of 386.
Use 4 as the next digit of our solution. 
Result so far: 16894.0
Subtracting 1592 from 1978 leaves us with 386.
Bring next digit (6) of the dividend behind the 386 and repeat the process: 3866 / 398

Step 8:
3866 divided by 398 is 9 with a remainder of 284.
Write down 9 as next digit of the result. 
Result so far: 168949.0
Deduct 3582 from 3866 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 9:
If we divide 2840 by 398, we get 7 and a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 168949.7
If we subtract 2786 from 2840, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 10:
398 can be fit into 540 1 times, resulting in a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 168949.71
Deduct 398 from 540 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 11:
398 goes into 1420 3 times with a remainder of 226.
Use 3 as the next digit of our solution. 
Result so far: 168949.713
Subtracting 1194 from 1420 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 12:
398 goes into 2260 5 times with a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 168949.7135
The remainder is 270 after subtracting 1990 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 13:
398 goes into 2700 6 times with a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 168949.71356
The remainder is 312 after subtracting 2388 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 14:
The number 398 fits into 3120 7 times, leaving a remainder of 334.
Write down 7 as next digit of the result. 
Result so far: 168949.713567
If we take 2786 away from 3120, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 15:
398 can be fit into 3340 8 times, resulting in a remainder of 156.
Use 8 as the next digit of our solution. 
Result so far: 168949.7135678
If we subtract 3184 from 3340, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 16:
The number 398 fits into 1560 3 times, leaving a remainder of 366.
Record the quotient 3 as the next digit in the result. 
Result so far: 168949.71356783
Subtracting 1194 from 1560 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

The final result is 168949.71356783 with a remainder of 3.66e-07.
