78626584 ÷ 376 
The aim is to understand the frequency of 376 in 78626584.

Step 1:
When dividing 7 by 376, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 376

On to step 2:
78 divided by 376 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 376

Moving on to step 3:
The number 376 fits into 786 2 times, leaving a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 752 from 786 to get 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 376

Let's proceed to step 4:
The number 376 fits into 342 0 times, leaving a remainder of 342.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 342 leaves us with 342.
Take the next digit (6) from the dividend and append it to 342, then repeat: 3426 / 376

On to step 5:
376 goes into 3426 9 times with a remainder of 42.
The next digit of our result is 9. 
Result so far: 209.0
Subtract 3384 from 3426 to get 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 376

On to step 6:
376 goes into 425 1 times with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 2091.0
Subtract 376 from 425 to get 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 376

Let's proceed to step 7:
When dividing 498 by 376, we get 1 with a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 20911.0
The remainder is 122 after subtracting 376 from 498.
Grab the next digit (4) from the dividend, add it to 122, then carry on: 1224 / 376

Step 8:
If we divide 1224 by 376, we get 3 and a remainder of 96.
Record the quotient 3 as the next digit in the result. 
Result so far: 209113.0
The remainder is 96 after subtracting 1128 from 1224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
The number 376 fits into 960 2 times, leaving a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 209113.2
Subtract 752 from 960 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 10:
2080 divided by 376 is 5 with a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 209113.25
Deduct 1880 from 2080 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
2000 divided by 376 is 5 with a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 209113.255
Deduct 1880 from 2000 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 209113.255 and a remainder of 0.012.
