7937998 divided by 806 
The aim is to understand the frequency of 806 in 7937998.

Let's proceed to step 1:
806 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 806

Advancing to step 2:
When dividing 79 by 806, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 806

Let's proceed to step 3:
806 can be fit into 793 0 times, resulting in a remainder of 793.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 793 to get 793.
Bring next digit (7) of the dividend behind the 793 and repeat the process: 7937 / 806

Moving on to step 4:
7937 divided by 806 is 9 with a remainder of 683.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 7254 from 7937 and we're left with 683.
Grab the next digit (9) from the dividend, add it to 683, then carry on: 6839 / 806

Moving on to step 5:
If we divide 6839 by 806, we get 8 and a remainder of 391.
Put 8 as the next digit of the answer. 
Result so far: 98.0
The remainder is 391 after subtracting 6448 from 6839.
Take the next digit (9) from the dividend and append it to 391, then repeat: 3919 / 806

Step 6:
3919 divided by 806 is 4 with a remainder of 695.
Put 4 as the next digit of the answer. 
Result so far: 984.0
If we take 3224 away from 3919, we end up with 695.
Append the next digit (8) from the dividend to 695 and continue with: 6958 / 806

On to step 7:
806 goes into 6958 8 times with a remainder of 510.
Record the quotient 8 as the next digit in the result. 
Result so far: 9848.0
Subtract 6448 from 6958 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 8:
806 can be fit into 5100 6 times, resulting in a remainder of 264.
The next digit of our result is 6. 
Result so far: 9848.6
If we subtract 4836 from 5100, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 9:
If we divide 2640 by 806, we get 3 and a remainder of 222.
Record the quotient 3 as the next digit in the result. 
Result so far: 9848.63
The remainder is 222 after subtracting 2418 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 10:
806 can be fit into 2220 2 times, resulting in a remainder of 608.
The number 2 becomes the next digit in our result. 
Result so far: 9848.632
Subtract 1612 from 2220 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 11:
If we divide 6080 by 806, we get 7 and a remainder of 438.
The number 7 becomes the next digit in our result. 
Result so far: 9848.6327
If we subtract 5642 from 6080, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 12:
If we divide 4380 by 806, we get 5 and a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 9848.63275
If we take 4030 away from 4380, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 13:
3500 divided by 806 is 4 with a remainder of 276.
Put 4 as the next digit of the answer. 
Result so far: 9848.632754
If we subtract 3224 from 3500, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 14:
806 can be fit into 2760 3 times, resulting in a remainder of 342.
Write down 3 as next digit of the result. 
Result so far: 9848.6327543
Subtract 2418 from 2760 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 15:
806 can be fit into 3420 4 times, resulting in a remainder of 196.
Record the quotient 4 as the next digit in the result. 
Result so far: 9848.63275434
If we take 3224 away from 3420, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final outcome is 9848.63275434, with a leftover of 1.96e-07.
