We're dividing 81360870 by 856 
The aim is to understand the frequency of 856 in 81360870.

Advancing to step 1:
856 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 856

Advancing to step 2:
856 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 856

Moving on to step 3:
813 divided by 856 is 0 with a remainder of 813.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 813 to get 813.
Include the next digit (6) from the dividend after 813, then repeat: 8136 / 856

Step 4:
If we divide 8136 by 856, we get 9 and a remainder of 432.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 432 after subtracting 7704 from 8136.
Include the next digit (0) from the dividend after 432, then repeat: 4320 / 856

On to step 5:
856 goes into 4320 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 95.0
The remainder is 40 after subtracting 4280 from 4320.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 856

Going ahead to step 6:
856 goes into 408 0 times with a remainder of 408.
Write down 0 as next digit of the result. 
Result so far: 950.0
Deduct 0 from 408 and we're left with 408.
Fetch the next digit (7) from the dividend, attach it to 408 and continue: 4087 / 856

Going ahead to step 7:
If we divide 4087 by 856, we get 4 and a remainder of 663.
Use 4 as the next digit of our solution. 
Result so far: 9504.0
Subtract 3424 from 4087 to get 663.
Take the next digit (0) from the dividend and append it to 663, then repeat: 6630 / 856

Step 8:
6630 divided by 856 is 7 with a remainder of 638.
Put 7 as the next digit of the answer. 
Result so far: 95047.0
If we take 5992 away from 6630, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Let's proceed to step 9:
The number 856 fits into 6380 7 times, leaving a remainder of 388.
Use 7 as the next digit of our solution. 
Result so far: 95047.7
The remainder is 388 after subtracting 5992 from 6380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 10:
If we divide 3880 by 856, we get 4 and a remainder of 456.
Use 4 as the next digit of our solution. 
Result so far: 95047.74
Subtract 3424 from 3880 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Moving on to step 11:
4560 divided by 856 is 5 with a remainder of 280.
The number 5 becomes the next digit in our result. 
Result so far: 95047.745
The remainder is 280 after subtracting 4280 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
856 goes into 2800 3 times with a remainder of 232.
Put 3 as the next digit of the answer. 
Result so far: 95047.7453
Subtract 2568 from 2800 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 13:
When dividing 2320 by 856, we get 2 with a remainder of 608.
Use 2 as the next digit of our solution. 
Result so far: 95047.74532
Subtract 1712 from 2320 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.

Step 14:
When dividing 6080 by 856, we get 7 with a remainder of 88.
Put 7 as the next digit of the answer. 
Result so far: 95047.745327
Subtracting 5992 from 6080 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 15:
When dividing 880 by 856, we get 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 95047.7453271
Deduct 856 from 880 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 16:
If we divide 240 by 856, we get 0 and a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 95047.7453271
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 95047.7453271 with a remaining 2.4e-07.
