7706586 ÷ 146 
The aim is to understand the frequency of 146 in 7706586.

On to step 1:
146 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 146

Let's proceed to step 2:
146 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 146

Advancing to step 3:
If we divide 770 by 146, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 730 from 770 to get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 146

On to step 4:
If we divide 406 by 146, we get 2 and a remainder of 114.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 114 after subtracting 292 from 406.
Grab the next digit (5) from the dividend, add it to 114, then carry on: 1145 / 146

On to step 5:
The number 146 fits into 1145 7 times, leaving a remainder of 123.
Record the quotient 7 as the next digit in the result. 
Result so far: 527.0
Subtract 1022 from 1145 to get 123.
Bring next digit (8) of the dividend behind the 123 and repeat the process: 1238 / 146

Going ahead to step 6:
If we divide 1238 by 146, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 5278.0
Deduct 1168 from 1238 and we're left with 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 146

Going ahead to step 7:
When dividing 706 by 146, we get 4 with a remainder of 122.
Write down 4 as next digit of the result. 
Result so far: 52784.0
Deduct 584 from 706 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 8:
The number 146 fits into 1220 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 52784.8
Subtract 1168 from 1220 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.

Advancing to step 9:
146 goes into 520 3 times with a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 52784.83
If we subtract 438 from 520, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
146 can be fit into 820 5 times, resulting in a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 52784.835
If we take 730 away from 820, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
When dividing 900 by 146, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 52784.8356
If we take 876 away from 900, we end up 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.

Let's proceed to step 12:
If we divide 240 by 146, we get 1 and a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 52784.83561
Deduct 146 from 240 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 13:
146 goes into 940 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 52784.835616
If we take 876 away from 940, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
When dividing 640 by 146, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 52784.8356164
Subtract 584 from 640 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 15:
When dividing 560 by 146, we get 3 with a remainder of 122.
Put 3 as the next digit of the answer. 
Result so far: 52784.83561643
Deduct 438 from 560 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The final outcome is 52784.83561643, with a leftover of 1.22e-07.
