We're dividing 70782702 by 897 
The aim is to understand the frequency of 897 in 70782702.

Advancing to step 1:
7 divided by 897 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 897

Moving on to step 2:
897 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 897

Going ahead to step 3:
When dividing 707 by 897, we get 0 with a remainder of 707.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 707, we end up with 707.
Append the next digit (8) from the dividend to 707 and continue with: 7078 / 897

Step 4:
If we divide 7078 by 897, we get 7 and a remainder of 799.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 6279 from 7078 and we're left with 799.
Append the next digit (2) from the dividend to 799 and continue with: 7992 / 897

Advancing to step 5:
The number 897 fits into 7992 8 times, leaving a remainder of 816.
Put 8 as the next digit of the answer. 
Result so far: 78.0
The remainder is 816 after subtracting 7176 from 7992.
Append the next digit (7) from the dividend to 816 and continue with: 8167 / 897

Let's proceed to step 6:
If we divide 8167 by 897, we get 9 and a remainder of 94.
The number 9 becomes the next digit in our result. 
Result so far: 789.0
If we take 8073 away from 8167, we end up with 94.
Grab the next digit (0) from the dividend, add it to 94, then carry on: 940 / 897

Step 7:
897 goes into 940 1 times with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 7891.0
Subtract 897 from 940 to get 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 897

Going ahead to step 8:
If we divide 432 by 897, we get 0 and a remainder of 432.
The next digit of our result is 0. 
Result so far: 78910.0
If we take 0 away from 432, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 9:
4320 divided by 897 is 4 with a remainder of 732.
Write down 4 as next digit of the result. 
Result so far: 78910.4
If we take 3588 away from 4320, we end up with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Step 10:
7320 divided by 897 is 8 with a remainder of 144.
The next digit of our result is 8. 
Result so far: 78910.48
If we subtract 7176 from 7320, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 11:
897 can be fit into 1440 1 times, resulting in a remainder of 543.
Write down 1 as next digit of the result. 
Result so far: 78910.481
Deduct 897 from 1440 and we're left with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

On to step 12:
The number 897 fits into 5430 6 times, leaving a remainder of 48.
The next digit of our result is 6. 
Result so far: 78910.4816
Subtracting 5382 from 5430 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
897 goes into 480 0 times with a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 78910.4816
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 14:
If we divide 4800 by 897, we get 5 and a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 78910.481605
Subtracting 4485 from 4800 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 15:
897 can be fit into 3150 3 times, resulting in a remainder of 459.
Put 3 as the next digit of the answer. 
Result so far: 78910.4816053
Deduct 2691 from 3150 and we're left with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Let's proceed to step 16:
When dividing 4590 by 897, we get 5 with a remainder of 105.
The next digit of our result is 5. 
Result so far: 78910.48160535
Deduct 4485 from 4590 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 78910.48160535 with a remainder of 1.05e-07.
