61626571 ÷ 797 
The aim is to understand the frequency of 797 in 61626571.

Going ahead to step 1:
6 divided by 797 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 797

Moving on to step 2:
If we divide 61 by 797, we get 0 and a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Fetch the next digit (6) from the dividend, attach it to 61 and continue: 616 / 797

On to step 3:
If we divide 616 by 797, we get 0 and a remainder of 616.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 616 and we're left with 616.
Grab the next digit (2) from the dividend, add it to 616, then carry on: 6162 / 797

Step 4:
The number 797 fits into 6162 7 times, leaving a remainder of 583.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 5579 from 6162 to get 583.
Grab the next digit (6) from the dividend, add it to 583, then carry on: 5836 / 797

Going ahead to step 5:
797 goes into 5836 7 times with a remainder of 257.
The next digit of our result is 7. 
Result so far: 77.0
Deduct 5579 from 5836 and we're left with 257.
Bring next digit (5) of the dividend behind the 257 and repeat the process: 2575 / 797

Let's proceed to step 6:
797 goes into 2575 3 times with a remainder of 184.
Use 3 as the next digit of our solution. 
Result so far: 773.0
Subtracting 2391 from 2575 leaves us with 184.
Bring next digit (7) of the dividend behind the 184 and repeat the process: 1847 / 797

Let's proceed to step 7:
1847 divided by 797 is 2 with a remainder of 253.
The next digit of our result is 2. 
Result so far: 7732.0
Deduct 1594 from 1847 and we're left with 253.
Append the next digit (1) from the dividend to 253 and continue with: 2531 / 797

Going ahead to step 8:
If we divide 2531 by 797, we get 3 and a remainder of 140.
The next digit of our result is 3. 
Result so far: 77323.0
If we take 2391 away from 2531, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 9:
797 goes into 1400 1 times with a remainder of 603.
Put 1 as the next digit of the answer. 
Result so far: 77323.1
Subtracting 797 from 1400 leaves us with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Step 10:
6030 divided by 797 is 7 with a remainder of 451.
The next digit of our result is 7. 
Result so far: 77323.17
If we subtract 5579 from 6030, we get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Advancing to step 11:
If we divide 4510 by 797, we get 5 and a remainder of 525.
The number 5 becomes the next digit in our result. 
Result so far: 77323.175
Deduct 3985 from 4510 and we're left with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Let's proceed to step 12:
797 can be fit into 5250 6 times, resulting in a remainder of 468.
Put 6 as the next digit of the answer. 
Result so far: 77323.1756
If we take 4782 away from 5250, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 13:
797 goes into 4680 5 times with a remainder of 695.
Write down 5 as next digit of the result. 
Result so far: 77323.17565
The remainder is 695 after subtracting 3985 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Advancing to step 14:
The number 797 fits into 6950 8 times, leaving a remainder of 574.
The next digit of our result is 8. 
Result so far: 77323.175658
If we take 6376 away from 6950, we end up with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Let's proceed to step 15:
797 can be fit into 5740 7 times, resulting in a remainder of 161.
Use 7 as the next digit of our solution. 
Result so far: 77323.1756587
Subtracting 5579 from 5740 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 16:
When dividing 1610 by 797, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 77323.17565872
If we take 1594 away from 1610, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 77323.17565872, with a leftover of 1.6e-08.
