80866264 divided by 146 
The aim is to understand the frequency of 146 in 80866264.

Step 1:
8 divided by 146 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 146

Advancing to step 2:
146 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 146

Going ahead to step 3:
808 divided by 146 is 5 with a remainder of 78.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 730 away from 808, we end up with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 146

Going ahead to step 4:
786 divided by 146 is 5 with a remainder of 56.
The next digit of our result is 5. 
Result so far: 55.0
If we subtract 730 from 786, we get 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 146

Moving on to step 5:
The number 146 fits into 566 3 times, leaving a remainder of 128.
The number 3 becomes the next digit in our result. 
Result so far: 553.0
Subtracting 438 from 566 leaves us with 128.
Fetch the next digit (2) from the dividend, attach it to 128 and continue: 1282 / 146

Step 6:
146 goes into 1282 8 times with a remainder of 114.
Record the quotient 8 as the next digit in the result. 
Result so far: 5538.0
Subtracting 1168 from 1282 leaves us with 114.
Bring next digit (6) of the dividend behind the 114 and repeat the process: 1146 / 146

Let's proceed to step 7:
When dividing 1146 by 146, we get 7 with a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 55387.0
If we subtract 1022 from 1146, we get 124.
Grab the next digit (4) from the dividend, add it to 124, then carry on: 1244 / 146

Going ahead to step 8:
1244 divided by 146 is 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 553878.0
Deduct 1168 from 1244 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
760 divided by 146 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 553878.5
The remainder is 30 after subtracting 730 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
When dividing 300 by 146, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 553878.52
If we subtract 292 from 300, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
When dividing 80 by 146, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 553878.52
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
146 goes into 800 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 553878.5205
Deduct 730 from 800 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
If we divide 700 by 146, we get 4 and a remainder of 116.
The next digit of our result is 4. 
Result so far: 553878.52054
Subtracting 584 from 700 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 14:
1160 divided by 146 is 7 with a remainder of 138.
Record the quotient 7 as the next digit in the result. 
Result so far: 553878.520547
If we take 1022 away from 1160, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 15:
When dividing 1380 by 146, we get 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 553878.5205479
If we subtract 1314 from 1380, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 16:
When dividing 660 by 146, we get 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 553878.52054794
If we take 584 away from 660, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 553878.52054794 and a remainder of 7.6e-08.
