We're dividing 87678772 by 943 
The aim is to understand the frequency of 943 in 87678772.

On to step 1:
When dividing 8 by 943, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 943

Let's proceed to step 2:
943 can be fit into 87 0 times, resulting in a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 943

Advancing to step 3:
943 can be fit into 876 0 times, resulting in a remainder of 876.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 876 leaves us with 876.
Include the next digit (7) from the dividend after 876, then repeat: 8767 / 943

On to step 4:
The number 943 fits into 8767 9 times, leaving a remainder of 280.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 8487 away from 8767, we end up with 280.
Bring next digit (8) of the dividend behind the 280 and repeat the process: 2808 / 943

Moving on to step 5:
When dividing 2808 by 943, we get 2 with a remainder of 922.
The next digit of our result is 2. 
Result so far: 92.0
Deduct 1886 from 2808 and we're left with 922.
Bring next digit (7) of the dividend behind the 922 and repeat the process: 9227 / 943

Moving on to step 6:
943 goes into 9227 9 times with a remainder of 740.
Write down 9 as next digit of the result. 
Result so far: 929.0
Subtracting 8487 from 9227 leaves us with 740.
Include the next digit (7) from the dividend after 740, then repeat: 7407 / 943

Let's proceed to step 7:
When dividing 7407 by 943, we get 7 with a remainder of 806.
Record the quotient 7 as the next digit in the result. 
Result so far: 9297.0
Subtracting 6601 from 7407 leaves us with 806.
Grab the next digit (2) from the dividend, add it to 806, then carry on: 8062 / 943

Advancing to step 8:
When dividing 8062 by 943, we get 8 with a remainder of 518.
Write down 8 as next digit of the result. 
Result so far: 92978.0
The remainder is 518 after subtracting 7544 from 8062.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Advancing to step 9:
943 can be fit into 5180 5 times, resulting in a remainder of 465.
The number 5 becomes the next digit in our result. 
Result so far: 92978.5
Subtracting 4715 from 5180 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Step 10:
If we divide 4650 by 943, we get 4 and a remainder of 878.
The number 4 becomes the next digit in our result. 
Result so far: 92978.54
Deduct 3772 from 4650 and we're left with 878.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8780, and continue the process.

Step 11:
943 goes into 8780 9 times with a remainder of 293.
Put 9 as the next digit of the answer. 
Result so far: 92978.549
Subtract 8487 from 8780 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Let's proceed to step 12:
The number 943 fits into 2930 3 times, leaving a remainder of 101.
Use 3 as the next digit of our solution. 
Result so far: 92978.5493
If we take 2829 away from 2930, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 13:
If we divide 1010 by 943, we get 1 and a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 92978.54931
The remainder is 67 after subtracting 943 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 14:
The number 943 fits into 670 0 times, leaving a remainder of 670.
The next digit of our result is 0. 
Result so far: 92978.54931
Subtract 0 from 670 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 15:
If we divide 6700 by 943, we get 7 and a remainder of 99.
Put 7 as the next digit of the answer. 
Result so far: 92978.5493107
Deduct 6601 from 6700 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 16:
The number 943 fits into 990 1 times, leaving a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 92978.54931071
If we subtract 943 from 990, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 92978.54931071 with a remainder of 4.7e-08.
