Let's divide 86586470 by 780
The aim is to understand the frequency of 780 in 86586470.

Moving on to step 1:
780 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 780

Moving on to step 2:
The number 780 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 780

Let's proceed to step 3:
780 goes into 865 1 times with a remainder of 85.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 780 from 865 leaves us with 85.
Append the next digit (8) from the dividend to 85 and continue with: 858 / 780

Step 4:
If we divide 858 by 780, we get 1 and a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 780 from 858 to get 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 780

Step 5:
If we divide 786 by 780, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 111.0
The remainder is 6 after subtracting 780 from 786.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 780

Advancing to step 6:
If we divide 64 by 780, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 1110.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (7) from the dividend, add it to 64, then carry on: 647 / 780

Moving on to step 7:
780 goes into 647 0 times with a remainder of 647.
Use 0 as the next digit of our solution. 
Result so far: 11100.0
Subtracting 0 from 647 leaves us with 647.
Include the next digit (0) from the dividend after 647, then repeat: 6470 / 780

On to step 8:
780 goes into 6470 8 times with a remainder of 230.
The next digit of our result is 8. 
Result so far: 111008.0
If we take 6240 away from 6470, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
780 goes into 2300 2 times with a remainder of 740.
Write down 2 as next digit of the result. 
Result so far: 111008.2
Deduct 1560 from 2300 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 10:
When dividing 7400 by 780, we get 9 with a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 111008.29
The remainder is 380 after subtracting 7020 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 11:
3800 divided by 780 is 4 with a remainder of 680.
The next digit of our result is 4. 
Result so far: 111008.294
Subtract 3120 from 3800 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 12:
780 goes into 6800 8 times with a remainder of 560.
Put 8 as the next digit of the answer. 
Result so far: 111008.2948
Subtracting 6240 from 6800 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 13:
If we divide 5600 by 780, we get 7 and a remainder of 140.
Write down 7 as next digit of the result. 
Result so far: 111008.29487
Deduct 5460 from 5600 and we're left 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 14:
The number 780 fits into 1400 1 times, leaving a remainder of 620.
The number 1 becomes the next digit in our result. 
Result so far: 111008.294871
The remainder is 620 after subtracting 780 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 15:
If we divide 6200 by 780, we get 7 and a remainder of 740.
Write down 7 as next digit of the result. 
Result so far: 111008.2948717
Deduct 5460 from 6200 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 16:
780 goes into 7400 9 times with a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 111008.29487179
Subtracting 7020 from 7400 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final outcome is 111008.29487179, with a leftover of 3.8e-07.
