We look at the division of 89777493 by 678 
The aim is to understand the frequency of 678 in 89777493.

Going ahead to step 1:
The number 678 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 678

On to step 2:
89 divided by 678 is 0 with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Grab the next digit (7) from the dividend, add it to 89, then carry on: 897 / 678

Advancing to step 3:
678 goes into 897 1 times with a remainder of 219.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 219 after subtracting 678 from 897.
Append the next digit (7) from the dividend to 219 and continue with: 2197 / 678

Let's proceed to step 4:
The number 678 fits into 2197 3 times, leaving a remainder of 163.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 2034 from 2197 and we're left with 163.
Grab the next digit (7) from the dividend, add it to 163, then carry on: 1637 / 678

Going ahead to step 5:
When dividing 1637 by 678, we get 2 with a remainder of 281.
Write down 2 as next digit of the result. 
Result so far: 132.0
Subtract 1356 from 1637 to get 281.
Grab the next digit (4) from the dividend, add it to 281, then carry on: 2814 / 678

Let's proceed to step 6:
The number 678 fits into 2814 4 times, leaving a remainder of 102.
The next digit of our result is 4. 
Result so far: 1324.0
The remainder is 102 after subtracting 2712 from 2814.
Grab the next digit (9) from the dividend, add it to 102, then carry on: 1029 / 678

On to step 7:
The number 678 fits into 1029 1 times, leaving a remainder of 351.
Record the quotient 1 as the next digit in the result. 
Result so far: 13241.0
If we subtract 678 from 1029, we get 351.
Include the next digit (3) from the dividend after 351, then repeat: 3513 / 678

On to step 8:
If we divide 3513 by 678, we get 5 and a remainder of 123.
The next digit of our result is 5. 
Result so far: 132415.0
Deduct 3390 from 3513 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 9:
The number 678 fits into 1230 1 times, leaving a remainder of 552.
The number 1 becomes the next digit in our result. 
Result so far: 132415.1
Subtract 678 from 1230 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 10:
678 goes into 5520 8 times with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 132415.18
Subtracting 5424 from 5520 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 11:
The number 678 fits into 960 1 times, leaving a remainder of 282.
The next digit of our result is 1. 
Result so far: 132415.181
If we subtract 678 from 960, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 12:
When dividing 2820 by 678, we get 4 with a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 132415.1814
If we take 2712 away from 2820, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 13:
678 goes into 1080 1 times with a remainder of 402.
The next digit of our result is 1. 
Result so far: 132415.18141
Deduct 678 from 1080 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 14:
678 can be fit into 4020 5 times, resulting in a remainder of 630.
The next digit of our result is 5. 
Result so far: 132415.181415
The remainder is 630 after subtracting 3390 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 15:
6300 divided by 678 is 9 with a remainder of 198.
Record the quotient 9 as the next digit in the result. 
Result so far: 132415.1814159
Subtracting 6102 from 6300 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 16:
678 can be fit into 1980 2 times, resulting in a remainder of 624.
Use 2 as the next digit of our solution. 
Result so far: 132415.18141592
The remainder is 624 after subtracting 1356 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

The final result is 132415.18141592 with a remainder of 6.24e-07.
