We're dividing 78580764 by 974 
The aim is to understand the frequency of 974 in 78580764.

Step 1:
974 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 974

On to step 2:
78 divided by 974 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 974

Going ahead to step 3:
When dividing 785 by 974, we get 0 with a remainder of 785.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 785 and we're left with 785.
Include the next digit (8) from the dividend after 785, then repeat: 7858 / 974

Going ahead to step 4:
When dividing 7858 by 974, we get 8 with a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 7792 from 7858 to get 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 974

Going ahead to step 5:
660 divided by 974 is 0 with a remainder of 660.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
The remainder is 660 after subtracting 0 from 660.
Append the next digit (7) from the dividend to 660 and continue with: 6607 / 974

Step 6:
When dividing 6607 by 974, we get 6 with a remainder of 763.
The next digit of our result is 6. 
Result so far: 806.0
Subtract 5844 from 6607 to get 763.
Take the next digit (6) from the dividend and append it to 763, then repeat: 7636 / 974

On to step 7:
The number 974 fits into 7636 7 times, leaving a remainder of 818.
Write down 7 as next digit of the result. 
Result so far: 8067.0
Subtract 6818 from 7636 to get 818.
Bring next digit (4) of the dividend behind the 818 and repeat the process: 8184 / 974

Moving on to step 8:
When dividing 8184 by 974, we get 8 with a remainder of 392.
The next digit of our result is 8. 
Result so far: 80678.0
Deduct 7792 from 8184 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 9:
If we divide 3920 by 974, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 80678.4
Subtract 3896 from 3920 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
The number 974 fits into 240 0 times, leaving a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 80678.4
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
If we divide 2400 by 974, we get 2 and a remainder of 452.
The number 2 becomes the next digit in our result. 
Result so far: 80678.402
Subtracting 1948 from 2400 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 12:
When dividing 4520 by 974, we get 4 with a remainder of 624.
Put 4 as the next digit of the answer. 
Result so far: 80678.4024
If we subtract 3896 from 4520, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 13:
When dividing 6240 by 974, we get 6 with a remainder of 396.
The number 6 becomes the next digit in our result. 
Result so far: 80678.40246
Deduct 5844 from 6240 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 14:
The number 974 fits into 3960 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 80678.402464
If we take 3896 away from 3960, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 15:
If we divide 640 by 974, we get 0 and a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 80678.402464
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 16:
974 goes into 6400 6 times with a remainder of 556.
Put 6 as the next digit of the answer. 
Result so far: 80678.40246406
Subtract 5844 from 6400 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

In conclusion, the division gives 80678.40246406 with a balance of 5.56e-07.
