67545779 divided by 402 
The aim is to understand the frequency of 402 in 67545779.

Going ahead to step 1:
The number 402 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 402

Step 2:
When dividing 67 by 402, we get 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Bring next digit (5) of the dividend behind the 67 and repeat the process: 675 / 402

Going ahead to step 3:
The number 402 fits into 675 1 times, leaving a remainder of 273.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 273 after subtracting 402 from 675.
Fetch the next digit (4) from the dividend, attach it to 273 and continue: 2734 / 402

Step 4:
The number 402 fits into 2734 6 times, leaving a remainder of 322.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 2412 from 2734 and we're left with 322.
Append the next digit (5) from the dividend to 322 and continue with: 3225 / 402

Advancing to step 5:
3225 divided by 402 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Subtract 3216 from 3225 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 402

Advancing to step 6:
The number 402 fits into 97 0 times, leaving a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 1680.0
Subtracting 0 from 97 leaves us with 97.
Grab the next digit (7) from the dividend, add it to 97, then carry on: 977 / 402

Moving on to step 7:
402 can be fit into 977 2 times, resulting in a remainder of 173.
Put 2 as the next digit of the answer. 
Result so far: 16802.0
Deduct 804 from 977 and we're left with 173.
Bring next digit (9) of the dividend behind the 173 and repeat the process: 1739 / 402

Let's proceed to step 8:
When dividing 1739 by 402, we get 4 with a remainder of 131.
The number 4 becomes the next digit in our result. 
Result so far: 168024.0
Subtract 1608 from 1739 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 9:
If we divide 1310 by 402, we get 3 and a remainder of 104.
Use 3 as the next digit of our solution. 
Result so far: 168024.3
Subtracting 1206 from 1310 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
When dividing 1040 by 402, we get 2 with a remainder of 236.
Record the quotient 2 as the next digit in the result. 
Result so far: 168024.32
Subtract 804 from 1040 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 11:
When dividing 2360 by 402, we get 5 with a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 168024.325
The remainder is 350 after subtracting 2010 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 12:
The number 402 fits into 3500 8 times, leaving a remainder of 284.
Use 8 as the next digit of our solution. 
Result so far: 168024.3258
Deduct 3216 from 3500 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 13:
When dividing 2840 by 402, we get 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 168024.32587
If we subtract 2814 from 2840, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
260 divided by 402 is 0 with a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 168024.32587
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 15:
2600 divided by 402 is 6 with a remainder of 188.
Record the quotient 6 as the next digit in the result. 
Result so far: 168024.3258706
If we take 2412 away from 2600, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 16:
402 can be fit into 1880 4 times, resulting in a remainder of 272.
Record the quotient 4 as the next digit in the result. 
Result so far: 168024.32587064
If we subtract 1608 from 1880, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The quotient of the division is 168024.32587064, and the remainder is 2.72e-07.
