We're dividing 67137889 by 399 
We want to figure out the number of times 67137889 can be divided by 399.

On to step 1:
When dividing 6 by 399, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 399

Step 2:
The number 399 fits into 67 0 times, leaving a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Append the next digit (1) from the dividend to 67 and continue with: 671 / 399

Moving on to step 3:
671 divided by 399 is 1 with a remainder of 272.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 399 away from 671, we end up with 272.
Bring next digit (3) of the dividend behind the 272 and repeat the process: 2723 / 399

Step 4:
2723 divided by 399 is 6 with a remainder of 329.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 2394 from 2723 and we're left with 329.
Include the next digit (7) from the dividend after 329, then repeat: 3297 / 399

Let's proceed to step 5:
The number 399 fits into 3297 8 times, leaving a remainder of 105.
Put 8 as the next digit of the answer. 
Result so far: 168.0
If we subtract 3192 from 3297, we get 105.
Fetch the next digit (8) from the dividend, attach it to 105 and continue: 1058 / 399

On to step 6:
When dividing 1058 by 399, we get 2 with a remainder of 260.
Put 2 as the next digit of the answer. 
Result so far: 1682.0
Subtract 798 from 1058 to get 260.
Take the next digit (8) from the dividend and append it to 260, then repeat: 2608 / 399

Going ahead to step 7:
399 goes into 2608 6 times with a remainder of 214.
Use 6 as the next digit of our solution. 
Result so far: 16826.0
Deduct 2394 from 2608 and we're left with 214.
Bring next digit (9) of the dividend behind the 214 and repeat the process: 2149 / 399

Going ahead to step 8:
If we divide 2149 by 399, we get 5 and a remainder of 154.
The number 5 becomes the next digit in our result. 
Result so far: 168265.0
If we subtract 1995 from 2149, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 9:
If we divide 1540 by 399, we get 3 and a remainder of 343.
The next digit of our result is 3. 
Result so far: 168265.3
Subtracting 1197 from 1540 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 10:
When dividing 3430 by 399, we get 8 with a remainder of 238.
The number 8 becomes the next digit in our result. 
Result so far: 168265.38
If we take 3192 away from 3430, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 11:
2380 divided by 399 is 5 with a remainder of 385.
Record the quotient 5 as the next digit in the result. 
Result so far: 168265.385
Subtracting 1995 from 2380 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 12:
399 goes into 3850 9 times with a remainder of 259.
The number 9 becomes the next digit in our result. 
Result so far: 168265.3859
Subtract 3591 from 3850 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 13:
399 goes into 2590 6 times with a remainder of 196.
Write down 6 as next digit of the result. 
Result so far: 168265.38596
If we take 2394 away from 2590, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 14:
1960 divided by 399 is 4 with a remainder of 364.
Record the quotient 4 as the next digit in the result. 
Result so far: 168265.385964
Deduct 1596 from 1960 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 15:
The number 399 fits into 3640 9 times, leaving a remainder of 49.
The next digit of our result is 9. 
Result so far: 168265.3859649
If we subtract 3591 from 3640, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 16:
When dividing 490 by 399, we get 1 with a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 168265.38596491
Subtract 399 from 490 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

The final result is 168265.38596491 with a remainder of 9.1e-08.
