81844624 ÷ 674 
The aim is to understand the frequency of 674 in 81844624.

Going ahead to step 1:
674 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 674

Let's proceed to step 2:
674 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 674

Moving on to step 3:
If we divide 818 by 674, we get 1 and a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 674 from 818, we get 144.
Include the next digit (4) from the dividend after 144, then repeat: 1444 / 674

Let's proceed to step 4:
674 can be fit into 1444 2 times, resulting in a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1348 from 1444 leaves us with 96.
Append the next digit (4) from the dividend to 96 and continue with: 964 / 674

Going ahead to step 5:
When dividing 964 by 674, we get 1 with a remainder of 290.
The next digit of our result is 1. 
Result so far: 121.0
Subtracting 674 from 964 leaves us with 290.
Append the next digit (6) from the dividend to 290 and continue with: 2906 / 674

On to step 6:
When dividing 2906 by 674, we get 4 with a remainder of 210.
Put 4 as the next digit of the answer. 
Result so far: 1214.0
Deduct 2696 from 2906 and we're left with 210.
Bring next digit (2) of the dividend behind the 210 and repeat the process: 2102 / 674

Advancing to step 7:
674 goes into 2102 3 times with a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 12143.0
Deduct 2022 from 2102 and we're left with 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 674

On to step 8:
804 divided by 674 is 1 with a remainder of 130.
The next digit of our result is 1. 
Result so far: 121431.0
Subtract 674 from 804 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 9:
If we divide 1300 by 674, we get 1 and a remainder of 626.
Record the quotient 1 as the next digit in the result. 
Result so far: 121431.1
The remainder is 626 after subtracting 674 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 10:
The number 674 fits into 6260 9 times, leaving a remainder of 194.
Write down 9 as next digit of the result. 
Result so far: 121431.19
If we take 6066 away from 6260, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 11:
674 goes into 1940 2 times with a remainder of 592.
Write down 2 as next digit of the result. 
Result so far: 121431.192
Deduct 1348 from 1940 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 12:
674 can be fit into 5920 8 times, resulting in a remainder of 528.
The next digit of our result is 8. 
Result so far: 121431.1928
Subtracting 5392 from 5920 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 13:
674 can be fit into 5280 7 times, resulting in a remainder of 562.
Put 7 as the next digit of the answer. 
Result so far: 121431.19287
Deduct 4718 from 5280 and we're left with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Moving on to step 14:
When dividing 5620 by 674, we get 8 with a remainder of 228.
The next digit of our result is 8. 
Result so far: 121431.192878
Subtract 5392 from 5620 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 15:
The number 674 fits into 2280 3 times, leaving a remainder of 258.
The number 3 becomes the next digit in our result. 
Result so far: 121431.1928783
If we take 2022 away from 2280, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 16:
2580 divided by 674 is 3 with a remainder of 558.
Put 3 as the next digit of the answer. 
Result so far: 121431.19287833
Subtracting 2022 from 2580 leaves us with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

After the division, we end up with 121431.19287833 and a remainder of 5.58e-07.
