We're dividing 99058027 by 678 
The aim is to understand the frequency of 678 in 99058027.

Moving on to step 1:
When dividing 9 by 678, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 678

On to step 2:
99 divided by 678 is 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Grab the next digit (0) from the dividend, add it to 99, then carry on: 990 / 678

Step 3:
990 divided by 678 is 1 with a remainder of 312.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 678 from 990 to get 312.
Append the next digit (5) from the dividend to 312 and continue with: 3125 / 678

Advancing to step 4:
678 can be fit into 3125 4 times, resulting in a remainder of 413.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 2712 away from 3125, we end up with 413.
Bring next digit (8) of the dividend behind the 413 and repeat the process: 4138 / 678

Moving on to step 5:
678 can be fit into 4138 6 times, resulting in a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 146.0
Subtracting 4068 from 4138 leaves us with 70.
Append the next digit (0) from the dividend to 70 and continue with: 700 / 678

Advancing to step 6:
The number 678 fits into 700 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1461.0
Deduct 678 from 700 and we're left with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 678

Advancing to step 7:
If we divide 222 by 678, we get 0 and a remainder of 222.
The number 0 becomes the next digit in our result. 
Result so far: 14610.0
Subtracting 0 from 222 leaves us with 222.
Grab the next digit (7) from the dividend, add it to 222, then carry on: 2227 / 678

Advancing to step 8:
When dividing 2227 by 678, we get 3 with a remainder of 193.
Put 3 as the next digit of the answer. 
Result so far: 146103.0
The remainder is 193 after subtracting 2034 from 2227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 9:
If we divide 1930 by 678, we get 2 and a remainder of 574.
Use 2 as the next digit of our solution. 
Result so far: 146103.2
The remainder is 574 after subtracting 1356 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Going ahead to step 10:
5740 divided by 678 is 8 with a remainder of 316.
Write down 8 as next digit of the result. 
Result so far: 146103.28
If we subtract 5424 from 5740, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 11:
If we divide 3160 by 678, we get 4 and a remainder of 448.
Record the quotient 4 as the next digit in the result. 
Result so far: 146103.284
If we take 2712 away from 3160, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 12:
4480 divided by 678 is 6 with a remainder of 412.
Use 6 as the next digit of our solution. 
Result so far: 146103.2846
If we take 4068 away from 4480, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 13:
678 goes into 4120 6 times with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 146103.28466
Subtract 4068 from 4120 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 146103.28466, with a leftover of 5.2e-05.
