We're dividing 85911026 by 851 
The aim is to understand the frequency of 851 in 85911026.

Going ahead to step 1:
When dividing 8 by 851, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 851

On to step 2:
When dividing 85 by 851, we get 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Include the next digit (9) from the dividend after 85, then repeat: 859 / 851

Advancing to step 3:
The number 851 fits into 859 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 851 from 859 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 851

Advancing to step 4:
When dividing 81 by 851, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 851

Let's proceed to step 5:
851 can be fit into 811 0 times, resulting in a remainder of 811.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we take 0 away from 811, we end up with 811.
Include the next digit (0) from the dividend after 811, then repeat: 8110 / 851

Moving on to step 6:
The number 851 fits into 8110 9 times, leaving a remainder of 451.
Put 9 as the next digit of the answer. 
Result so far: 1009.0
The remainder is 451 after subtracting 7659 from 8110.
Take the next digit (2) from the dividend and append it to 451, then repeat: 4512 / 851

Moving on to step 7:
851 goes into 4512 5 times with a remainder of 257.
Record the quotient 5 as the next digit in the result. 
Result so far: 10095.0
If we take 4255 away from 4512, we end up with 257.
Bring next digit (6) of the dividend behind the 257 and repeat the process: 2576 / 851

Going ahead to step 8:
851 can be fit into 2576 3 times, resulting in a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 100953.0
Subtract 2553 from 2576 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
851 can be fit into 230 0 times, resulting in a remainder of 230.
The next digit of our result is 0. 
Result so far: 100953.0
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
If we divide 2300 by 851, we get 2 and a remainder of 598.
Write down 2 as next digit of the result. 
Result so far: 100953.02
If we take 1702 away from 2300, we end up 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.

Step 11:
When dividing 5980 by 851, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 100953.027
The remainder is 23 after subtracting 5957 from 5980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 12:
The number 851 fits into 230 0 times, leaving a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 100953.027
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 13:
851 goes into 2300 2 times with a remainder of 598.
Use 2 as the next digit of our solution. 
Result so far: 100953.02702
Subtract 1702 from 2300 to get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 14:
851 can be fit into 5980 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 100953.027027
If we take 5957 away from 5980, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 15:
230 divided by 851 is 0 with a remainder of 230.
The next digit of our result is 0. 
Result so far: 100953.027027
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 16:
When dividing 2300 by 851, we get 2 with a remainder of 598.
The number 2 becomes the next digit in our result. 
Result so far: 100953.02702702
Subtracting 1702 from 2300 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 outcome is 100953.02702702, with a leftover of 5.98e-07.
