We divide 938830 by 86
The aim is to understand the frequency of 86 in 938830.

Going ahead to step 1:
If we divide 9 by 86, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 86

Let's proceed to step 2:
93 divided by 86 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 86 away from 93, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 86

Advancing to step 3:
78 divided by 86 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 86

Going ahead to step 4:
86 goes into 788 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we subtract 774 from 788, we get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 86

Step 5:
143 divided by 86 is 1 with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1091.0
If we subtract 86 from 143, we get 57.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 86

Moving on to step 6:
If we divide 570 by 86, we get 6 and a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 10916.0
Subtracting 516 from 570 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
86 goes into 540 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 10916.6
Deduct 516 from 540 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
When dividing 240 by 86, we get 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 10916.62
Subtracting 172 from 240 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
If we divide 680 by 86, we get 7 and a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 10916.627
Deduct 602 from 680 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 10:
The number 86 fits into 780 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 10916.6279
If we subtract 774 from 780, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
86 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 10916.6279
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
86 can be fit into 600 6 times, resulting in a remainder of 84.
The next digit of our result is 6. 
Result so far: 10916.627906
If we take 516 away from 600, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 13:
The number 86 fits into 840 9 times, leaving a remainder of 66.
The next digit of our result is 9. 
Result so far: 10916.6279069
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 14:
When dividing 660 by 86, we get 7 with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 10916.62790697
Deduct 602 from 660 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 10916.62790697, and the remainder is 5.8e-08.
