We're dividing 86978138 by 923 
The aim is to understand the frequency of 923 in 86978138.

Moving on to step 1:
If we divide 8 by 923, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 923

Let's proceed to step 2:
The number 923 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 923

Going ahead to step 3:
923 goes into 869 0 times with a remainder of 869.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 869, we end up with 869.
Bring next digit (7) of the dividend behind the 869 and repeat the process: 8697 / 923

On to step 4:
The number 923 fits into 8697 9 times, leaving a remainder of 390.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 8307 from 8697 to get 390.
Append the next digit (8) from the dividend to 390 and continue with: 3908 / 923

Let's proceed to step 5:
923 goes into 3908 4 times with a remainder of 216.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Deduct 3692 from 3908 and we're left with 216.
Append the next digit (1) from the dividend to 216 and continue with: 2161 / 923

On to step 6:
2161 divided by 923 is 2 with a remainder of 315.
Write down 2 as next digit of the result. 
Result so far: 942.0
If we subtract 1846 from 2161, we get 315.
Fetch the next digit (3) from the dividend, attach it to 315 and continue: 3153 / 923

Going ahead to step 7:
If we divide 3153 by 923, we get 3 and a remainder of 384.
The number 3 becomes the next digit in our result. 
Result so far: 9423.0
Subtracting 2769 from 3153 leaves us with 384.
Bring next digit (8) of the dividend behind the 384 and repeat the process: 3848 / 923

Let's proceed to step 8:
3848 divided by 923 is 4 with a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 94234.0
Subtracting 3692 from 3848 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 9:
1560 divided by 923 is 1 with a remainder of 637.
Put 1 as the next digit of the answer. 
Result so far: 94234.1
If we subtract 923 from 1560, we get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

On to step 10:
If we divide 6370 by 923, we get 6 and a remainder of 832.
Record the quotient 6 as the next digit in the result. 
Result so far: 94234.16
Deduct 5538 from 6370 and we're left with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Going ahead to step 11:
923 goes into 8320 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 94234.169
If we subtract 8307 from 8320, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
If we divide 130 by 923, we get 0 and a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 94234.169
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 13:
923 can be fit into 1300 1 times, resulting in a remainder of 377.
The next digit of our result is 1. 
Result so far: 94234.16901
If we subtract 923 from 1300, we get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 14:
923 goes into 3770 4 times with a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 94234.169014
Deduct 3692 from 3770 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 15:
If we divide 780 by 923, we get 0 and a remainder of 780.
Record the quotient 0 as the next digit in the result. 
Result so far: 94234.169014
Subtracting 0 from 780 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

On to step 16:
If we divide 7800 by 923, we get 8 and a remainder of 416.
The next digit of our result is 8. 
Result so far: 94234.16901408
Deduct 7384 from 7800 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Our division results in 94234.16901408 with a remaining 4.16e-07.
