12050817 ÷ 994 
The aim is to understand the frequency of 994 in 12050817.

On to step 1:
1 divided by 994 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 994

Advancing to step 2:
If we divide 12 by 994, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 994

On to step 3:
120 divided by 994 is 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 120 after subtracting 0 from 120.
Take the next digit (5) from the dividend and append it to 120, then repeat: 1205 / 994

Step 4:
1205 divided by 994 is 1 with a remainder of 211.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 211 after subtracting 994 from 1205.
Grab the next digit (0) from the dividend, add it to 211, then carry on: 2110 / 994

Step 5:
When dividing 2110 by 994, we get 2 with a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1988 from 2110 and we're left with 122.
Bring next digit (8) of the dividend behind the 122 and repeat the process: 1228 / 994

Step 6:
The number 994 fits into 1228 1 times, leaving a remainder of 234.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
If we subtract 994 from 1228, we get 234.
Fetch the next digit (1) from the dividend, attach it to 234 and continue: 2341 / 994

Advancing to step 7:
When dividing 2341 by 994, we get 2 with a remainder of 353.
The next digit of our result is 2. 
Result so far: 1212.0
Deduct 1988 from 2341 and we're left with 353.
Take the next digit (7) from the dividend and append it to 353, then repeat: 3537 / 994

Moving on to step 8:
994 goes into 3537 3 times with a remainder of 555.
The next digit of our result is 3. 
Result so far: 12123.0
Subtract 2982 from 3537 to get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 9:
If we divide 5550 by 994, we get 5 and a remainder of 580.
Write down 5 as next digit of the result. 
Result so far: 12123.5
Subtract 4970 from 5550 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 10:
994 can be fit into 5800 5 times, resulting in a remainder of 830.
Use 5 as the next digit of our solution. 
Result so far: 12123.55
If we subtract 4970 from 5800, we get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

The quotient of the division is 12123.55, and the remainder is 0.83.
