We divide 78801611 by 67
The aim is to understand the frequency of 67 in 78801611.

Step 1:
If we divide 7 by 67, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 67

Moving on to step 2:
67 goes into 78 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 67 from 78, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 67

Moving on to step 3:
If we divide 118 by 67, we get 1 and a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 67 from 118 leaves us with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 67

Moving on to step 4:
67 can be fit into 510 7 times, resulting in a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Deduct 469 from 510 and we're left with 41.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 67

Step 5:
The number 67 fits into 411 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 1176.0
Subtract 402 from 411 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 67

On to step 6:
96 divided by 67 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 11761.0
If we take 67 away from 96, we end up with 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 67

Moving on to step 7:
When dividing 291 by 67, we get 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 117614.0
If we subtract 268 from 291, we get 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 67

On to step 8:
The number 67 fits into 231 3 times, leaving a remainder of 30.
The next digit of our result is 3. 
Result so far: 1176143.0
If we take 201 away from 231, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 67 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 1176143.4
Subtract 268 from 300 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
If we divide 320 by 67, we get 4 and a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 1176143.44
Subtracting 268 from 320 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 1176143.44 with a remainder of 0.052.
