We look at the division of 53506505 by 806 
The aim is to understand the frequency of 806 in 53506505.

Going ahead to step 1:
806 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 806

Going ahead to step 2:
When dividing 53 by 806, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 806

Step 3:
If we divide 535 by 806, we get 0 and a remainder of 535.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 535 to get 535.
Grab the next digit (0) from the dividend, add it to 535, then carry on: 5350 / 806

Going ahead to step 4:
If we divide 5350 by 806, we get 6 and a remainder of 514.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 514 after subtracting 4836 from 5350.
Take the next digit (6) from the dividend and append it to 514, then repeat: 5146 / 806

On to step 5:
5146 divided by 806 is 6 with a remainder of 310.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtract 4836 from 5146 to get 310.
Include the next digit (5) from the dividend after 310, then repeat: 3105 / 806

Let's proceed to step 6:
The number 806 fits into 3105 3 times, leaving a remainder of 687.
Record the quotient 3 as the next digit in the result. 
Result so far: 663.0
Deduct 2418 from 3105 and we're left with 687.
Bring next digit (0) of the dividend behind the 687 and repeat the process: 6870 / 806

Step 7:
When dividing 6870 by 806, we get 8 with a remainder of 422.
The number 8 becomes the next digit in our result. 
Result so far: 6638.0
Deduct 6448 from 6870 and we're left with 422.
Grab the next digit (5) from the dividend, add it to 422, then carry on: 4225 / 806

Step 8:
The number 806 fits into 4225 5 times, leaving a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 66385.0
The remainder is 195 after subtracting 4030 from 4225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 9:
The number 806 fits into 1950 2 times, leaving a remainder of 338.
Use 2 as the next digit of our solution. 
Result so far: 66385.2
Subtracting 1612 from 1950 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 10:
806 goes into 3380 4 times with a remainder of 156.
Use 4 as the next digit of our solution. 
Result so far: 66385.24
Subtract 3224 from 3380 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 11:
If we divide 1560 by 806, we get 1 and a remainder of 754.
Put 1 as the next digit of the answer. 
Result so far: 66385.241
If we subtract 806 from 1560, we get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Step 12:
7540 divided by 806 is 9 with a remainder of 286.
Use 9 as the next digit of our solution. 
Result so far: 66385.2419
Deduct 7254 from 7540 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 13:
The number 806 fits into 2860 3 times, leaving a remainder of 442.
Write down 3 as next digit of the result. 
Result so far: 66385.24193
Deduct 2418 from 2860 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 14:
If we divide 4420 by 806, we get 5 and a remainder of 390.
The number 5 becomes the next digit in our result. 
Result so far: 66385.241935
Subtracting 4030 from 4420 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 15:
806 goes into 3900 4 times with a remainder of 676.
Write down 4 as next digit of the result. 
Result so far: 66385.2419354
Subtract 3224 from 3900 to get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Step 16:
806 goes into 6760 8 times with a remainder of 312.
The next digit of our result is 8. 
Result so far: 66385.24193548
The remainder is 312 after subtracting 6448 from 6760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The quotient of the division is 66385.24193548, and the remainder is 3.12e-07.
