We look at the division of 85480948 by 813 
The aim is to understand the frequency of 813 in 85480948.

Step 1:
When dividing 8 by 813, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 813

Advancing to step 2:
When dividing 85 by 813, we get 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Fetch the next digit (4) from the dividend, attach it to 85 and continue: 854 / 813

Let's proceed to step 3:
813 can be fit into 854 1 times, resulting in a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 813 away from 854, we end up with 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 813

Going ahead to step 4:
418 divided by 813 is 0 with a remainder of 418.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 418 leaves us with 418.
Fetch the next digit (0) from the dividend, attach it to 418 and continue: 4180 / 813

Let's proceed to step 5:
If we divide 4180 by 813, we get 5 and a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Deduct 4065 from 4180 and we're left with 115.
Bring next digit (9) of the dividend behind the 115 and repeat the process: 1159 / 813

Step 6:
813 can be fit into 1159 1 times, resulting in a remainder of 346.
Use 1 as the next digit of our solution. 
Result so far: 1051.0
The remainder is 346 after subtracting 813 from 1159.
Bring next digit (4) of the dividend behind the 346 and repeat the process: 3464 / 813

Advancing to step 7:
813 goes into 3464 4 times with a remainder of 212.
Use 4 as the next digit of our solution. 
Result so far: 10514.0
Subtracting 3252 from 3464 leaves us with 212.
Bring next digit (8) of the dividend behind the 212 and repeat the process: 2128 / 813

Let's proceed to step 8:
When dividing 2128 by 813, we get 2 with a remainder of 502.
Write down 2 as next digit of the result. 
Result so far: 105142.0
If we subtract 1626 from 2128, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

On to step 9:
When dividing 5020 by 813, we get 6 with a remainder of 142.
The number 6 becomes the next digit in our result. 
Result so far: 105142.6
The remainder is 142 after subtracting 4878 from 5020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 10:
813 goes into 1420 1 times with a remainder of 607.
Put 1 as the next digit of the answer. 
Result so far: 105142.61
Subtract 813 from 1420 to get 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Step 11:
If we divide 6070 by 813, we get 7 and a remainder of 379.
Put 7 as the next digit of the answer. 
Result so far: 105142.617
Subtract 5691 from 6070 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Going ahead to step 12:
813 can be fit into 3790 4 times, resulting in a remainder of 538.
Write down 4 as next digit of the result. 
Result so far: 105142.6174
Deduct 3252 from 3790 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

On to step 13:
When dividing 5380 by 813, we get 6 with a remainder of 502.
Write down 6 as next digit of the result. 
Result so far: 105142.61746
Subtracting 4878 from 5380 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Let's proceed to step 14:
The number 813 fits into 5020 6 times, leaving a remainder of 142.
Put 6 as the next digit of the answer. 
Result so far: 105142.617466
If we take 4878 away from 5020, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final result is 105142.617466 with a remainder of 1.42e-05.
