67389636 divided by 402 
We want to figure out the number of times 67389636 can be divided by 402.

Let's proceed to step 1:
If we divide 6 by 402, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 402

Let's proceed to step 2:
The number 402 fits into 67 0 times, leaving a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Append the next digit (3) from the dividend to 67 and continue with: 673 / 402

On to step 3:
673 divided by 402 is 1 with a remainder of 271.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 402 from 673 leaves us with 271.
Grab the next digit (8) from the dividend, add it to 271, then carry on: 2718 / 402

Advancing to step 4:
402 can be fit into 2718 6 times, resulting in a remainder of 306.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 2412 from 2718 to get 306.
Fetch the next digit (9) from the dividend, attach it to 306 and continue: 3069 / 402

Going ahead to step 5:
If we divide 3069 by 402, we get 7 and a remainder of 255.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
Deduct 2814 from 3069 and we're left with 255.
Fetch the next digit (6) from the dividend, attach it to 255 and continue: 2556 / 402

Let's proceed to step 6:
402 goes into 2556 6 times with a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 1676.0
Subtract 2412 from 2556 to get 144.
Append the next digit (3) from the dividend to 144 and continue with: 1443 / 402

Moving on to step 7:
If we divide 1443 by 402, we get 3 and a remainder of 237.
Use 3 as the next digit of our solution. 
Result so far: 16763.0
Subtracting 1206 from 1443 leaves us with 237.
Take the next digit (6) from the dividend and append it to 237, then repeat: 2376 / 402

On to step 8:
2376 divided by 402 is 5 with a remainder of 366.
Put 5 as the next digit of the answer. 
Result so far: 167635.0
If we subtract 2010 from 2376, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 9:
When dividing 3660 by 402, we get 9 with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 167635.9
Subtracting 3618 from 3660 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
When dividing 420 by 402, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 167635.91
If we take 402 away from 420, we end up 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.

Let's proceed to step 11:
If we divide 180 by 402, we get 0 and a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 167635.91
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 12:
402 can be fit into 1800 4 times, resulting in a remainder of 192.
The next digit of our result is 4. 
Result so far: 167635.9104
Deduct 1608 from 1800 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 13:
402 can be fit into 1920 4 times, resulting in a remainder of 312.
Put 4 as the next digit of the answer. 
Result so far: 167635.91044
If we subtract 1608 from 1920, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Our division results in 167635.91044 with a remaining 0.000312.
