42500886 ÷ 994 
The aim is to understand the frequency of 994 in 42500886.

Let's proceed to step 1:
If we divide 4 by 994, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 994

Going ahead to step 2:
994 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 994

Moving on to step 3:
994 can be fit into 425 0 times, resulting in a remainder of 425.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 425 to get 425.
Fetch the next digit (0) from the dividend, attach it to 425 and continue: 4250 / 994

Advancing to step 4:
994 can be fit into 4250 4 times, resulting in a remainder of 274.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3976 from 4250 to get 274.
Grab the next digit (0) from the dividend, add it to 274, then carry on: 2740 / 994

Going ahead to step 5:
994 goes into 2740 2 times with a remainder of 752.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 1988 from 2740 and we're left with 752.
Grab the next digit (8) from the dividend, add it to 752, then carry on: 7528 / 994

Advancing to step 6:
The number 994 fits into 7528 7 times, leaving a remainder of 570.
Record the quotient 7 as the next digit in the result. 
Result so far: 427.0
If we subtract 6958 from 7528, we get 570.
Take the next digit (8) from the dividend and append it to 570, then repeat: 5708 / 994

Step 7:
The number 994 fits into 5708 5 times, leaving a remainder of 738.
Record the quotient 5 as the next digit in the result. 
Result so far: 4275.0
If we subtract 4970 from 5708, we get 738.
Fetch the next digit (6) from the dividend, attach it to 738 and continue: 7386 / 994

Step 8:
When dividing 7386 by 994, we get 7 with a remainder of 428.
The next digit of our result is 7. 
Result so far: 42757.0
If we take 6958 away from 7386, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 9:
If we divide 4280 by 994, we get 4 and a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 42757.4
If we subtract 3976 from 4280, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 10:
994 goes into 3040 3 times with a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 42757.43
Subtracting 2982 from 3040 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
994 goes into 580 0 times with a remainder of 580.
The number 0 becomes the next digit in our result. 
Result so far: 42757.43
Deduct 0 from 580 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 12:
The number 994 fits into 5800 5 times, leaving a remainder of 830.
The next digit of our result is 5. 
Result so far: 42757.4305
If we take 4970 away from 5800, we end up with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Going ahead to step 13:
The number 994 fits into 8300 8 times, leaving a remainder of 348.
The next digit of our result is 8. 
Result so far: 42757.43058
The remainder is 348 after subtracting 7952 from 8300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 14:
994 goes into 3480 3 times with a remainder of 498.
Record the quotient 3 as the next digit in the result. 
Result so far: 42757.430583
If we subtract 2982 from 3480, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 15:
4980 divided by 994 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 42757.4305835
If we subtract 4970 from 4980, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 16:
If we divide 100 by 994, we get 0 and a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 42757.4305835
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 42757.4305835, with a leftover of 1e-07.
