1973821 ÷ 798 
The aim is to understand the frequency of 798 in 1973821.

Let's proceed to step 1:
The number 798 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 798

Moving on to step 2:
When dividing 19 by 798, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 798

Moving on to step 3:
When dividing 197 by 798, we get 0 with a remainder of 197.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 197, we get 197.
Grab the next digit (3) from the dividend, add it to 197, then carry on: 1973 / 798

Step 4:
798 goes into 1973 2 times with a remainder of 377.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1596 from 1973 and we're left with 377.
Take the next digit (8) from the dividend and append it to 377, then repeat: 3778 / 798

Going ahead to step 5:
798 goes into 3778 4 times with a remainder of 586.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 3192 from 3778, we get 586.
Bring next digit (2) of the dividend behind the 586 and repeat the process: 5862 / 798

Step 6:
798 goes into 5862 7 times with a remainder of 276.
The next digit of our result is 7. 
Result so far: 247.0
Deduct 5586 from 5862 and we're left with 276.
Take the next digit (1) from the dividend and append it to 276, then repeat: 2761 / 798

On to step 7:
The number 798 fits into 2761 3 times, leaving a remainder of 367.
The number 3 becomes the next digit in our result. 
Result so far: 2473.0
If we subtract 2394 from 2761, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Advancing to step 8:
The number 798 fits into 3670 4 times, leaving a remainder of 478.
Put 4 as the next digit of the answer. 
Result so far: 2473.4
If we subtract 3192 from 3670, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 9:
4780 divided by 798 is 5 with a remainder of 790.
Put 5 as the next digit of the answer. 
Result so far: 2473.45
If we take 3990 away from 4780, we end up with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 10:
798 goes into 7900 9 times with a remainder of 718.
Use 9 as the next digit of our solution. 
Result so far: 2473.459
Subtract 7182 from 7900 to get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Moving on to step 11:
When dividing 7180 by 798, we get 8 with a remainder of 796.
The next digit of our result is 8. 
Result so far: 2473.4598
If we subtract 6384 from 7180, we get 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Advancing to step 12:
7960 divided by 798 is 9 with a remainder of 778.
Record the quotient 9 as the next digit in the result. 
Result so far: 2473.45989
The remainder is 778 after subtracting 7182 from 7960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Advancing to step 13:
The number 798 fits into 7780 9 times, leaving a remainder of 598.
Write down 9 as next digit of the result. 
Result so far: 2473.459899
Subtracting 7182 from 7780 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

The final result is 2473.459899 with a remainder of 5.98e-05.
