Let's divide 70867840 by 823
The aim is to understand the frequency of 823 in 70867840.

On to step 1:
823 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 823

Advancing to step 2:
70 divided by 823 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Bring next digit (8) of the dividend behind the 70 and repeat the process: 708 / 823

Advancing to step 3:
823 goes into 708 0 times with a remainder of 708.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 708 to get 708.
Grab the next digit (6) from the dividend, add it to 708, then carry on: 7086 / 823

Going ahead to step 4:
823 can be fit into 7086 8 times, resulting in a remainder of 502.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 6584 from 7086 to get 502.
Append the next digit (7) from the dividend to 502 and continue with: 5027 / 823

Moving on to step 5:
When dividing 5027 by 823, we get 6 with a remainder of 89.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Deduct 4938 from 5027 and we're left with 89.
Take the next digit (8) from the dividend and append it to 89, then repeat: 898 / 823

Going ahead to step 6:
823 goes into 898 1 times with a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 861.0
If we take 823 away from 898, we end up with 75.
Append the next digit (4) from the dividend to 75 and continue with: 754 / 823

Step 7:
If we divide 754 by 823, we get 0 and a remainder of 754.
Put 0 as the next digit of the answer. 
Result so far: 8610.0
The remainder is 754 after subtracting 0 from 754.
Append the next digit (0) from the dividend to 754 and continue with: 7540 / 823

Let's proceed to step 8:
7540 divided by 823 is 9 with a remainder of 133.
The next digit of our result is 9. 
Result so far: 86109.0
Deduct 7407 from 7540 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 9:
The number 823 fits into 1330 1 times, leaving a remainder of 507.
Record the quotient 1 as the next digit in the result. 
Result so far: 86109.1
The remainder is 507 after subtracting 823 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Going ahead to step 10:
5070 divided by 823 is 6 with a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 86109.16
The remainder is 132 after subtracting 4938 from 5070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 11:
When dividing 1320 by 823, we get 1 with a remainder of 497.
Put 1 as the next digit of the answer. 
Result so far: 86109.161
Deduct 823 from 1320 and we're left with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

On to step 12:
4970 divided by 823 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 86109.1616
Subtract 4938 from 4970 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
320 divided by 823 is 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 86109.1616
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
823 can be fit into 3200 3 times, resulting in a remainder of 731.
Use 3 as the next digit of our solution. 
Result so far: 86109.161603
Deduct 2469 from 3200 and we're left with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

On to step 15:
823 goes into 7310 8 times with a remainder of 726.
Write down 8 as next digit of the result. 
Result so far: 86109.1616038
If we subtract 6584 from 7310, we get 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Going ahead to step 16:
If we divide 7260 by 823, we get 8 and a remainder of 676.
Put 8 as the next digit of the answer. 
Result so far: 86109.16160388
The remainder is 676 after subtracting 6584 from 7260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

The final result is 86109.16160388 with a remainder of 6.76e-07.
