Let's divide 78490141 by 86
The aim is to understand the frequency of 86 in 78490141.

Moving on to step 1:
86 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 86

Advancing to step 2:
If we divide 78 by 86, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 86

Moving on to step 3:
784 divided by 86 is 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 774 from 784 to get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 86

Moving on to step 4:
109 divided by 86 is 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 91.0
Deduct 86 from 109 and we're left with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 86

Let's proceed to step 5:
230 divided by 86 is 2 with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 912.0
Subtract 172 from 230 to get 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 86

Moving on to step 6:
When dividing 581 by 86, we get 6 with a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 9126.0
Deduct 516 from 581 and we're left with 65.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 86

Let's proceed to step 7:
86 goes into 654 7 times with a remainder of 52.
The next digit of our result is 7. 
Result so far: 91267.0
If we subtract 602 from 654, we get 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 86

Moving on to step 8:
86 can be fit into 521 6 times, resulting in a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 912676.0
If we take 516 away from 521, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
The number 86 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 912676.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
The number 86 fits into 500 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 912676.05
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
The number 86 fits into 700 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 912676.058
Deduct 688 from 700 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 86, we get 1 and a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 912676.0581
If we take 86 away from 120, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
When dividing 340 by 86, we get 3 with a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 912676.05813
The remainder is 82 after subtracting 258 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 14:
86 goes into 820 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 912676.058139
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 15:
86 goes into 460 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 912676.0581395
Deduct 430 from 460 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 16:
If we divide 300 by 86, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 912676.05813953
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 912676.05813953 and a remainder of 4.2e-08.
