Let's divide 97870048 by 823
The aim is to understand the frequency of 823 in 97870048.

On to step 1:
When dividing 9 by 823, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 823

Let's proceed to step 2:
823 goes into 97 0 times with a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Bring next digit (8) of the dividend behind the 97 and repeat the process: 978 / 823

Let's proceed to step 3:
When dividing 978 by 823, we get 1 with a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 823 away from 978, we end up with 155.
Bring next digit (7) of the dividend behind the 155 and repeat the process: 1557 / 823

Let's proceed to step 4:
823 can be fit into 1557 1 times, resulting in a remainder of 734.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 823 from 1557, we get 734.
Grab the next digit (0) from the dividend, add it to 734, then carry on: 7340 / 823

Let's proceed to step 5:
823 goes into 7340 8 times with a remainder of 756.
Write down 8 as next digit of the result. 
Result so far: 118.0
If we subtract 6584 from 7340, we get 756.
Append the next digit (0) from the dividend to 756 and continue with: 7560 / 823

On to step 6:
The number 823 fits into 7560 9 times, leaving a remainder of 153.
Write down 9 as next digit of the result. 
Result so far: 1189.0
If we subtract 7407 from 7560, we get 153.
Grab the next digit (4) from the dividend, add it to 153, then carry on: 1534 / 823

Going ahead to step 7:
If we divide 1534 by 823, we get 1 and a remainder of 711.
Put 1 as the next digit of the answer. 
Result so far: 11891.0
Subtracting 823 from 1534 leaves us with 711.
Append the next digit (8) from the dividend to 711 and continue with: 7118 / 823

Let's proceed to step 8:
When dividing 7118 by 823, we get 8 with a remainder of 534.
Use 8 as the next digit of our solution. 
Result so far: 118918.0
The remainder is 534 after subtracting 6584 from 7118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 9:
823 can be fit into 5340 6 times, resulting in a remainder of 402.
Use 6 as the next digit of our solution. 
Result so far: 118918.6
Deduct 4938 from 5340 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 10:
When dividing 4020 by 823, we get 4 with a remainder of 728.
Put 4 as the next digit of the answer. 
Result so far: 118918.64
Subtracting 3292 from 4020 leaves us with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Advancing to step 11:
823 goes into 7280 8 times with a remainder of 696.
Write down 8 as next digit of the result. 
Result so far: 118918.648
Subtracting 6584 from 7280 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Step 12:
If we divide 6960 by 823, we get 8 and a remainder of 376.
Write down 8 as next digit of the result. 
Result so far: 118918.6488
Subtracting 6584 from 6960 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final outcome is 118918.6488, with a leftover of 0.00376.
