We're dividing 45286301 by 690 
The aim is to understand the frequency of 690 in 45286301.

Step 1:
690 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 690

Advancing to step 2:
The number 690 fits into 45 0 times, leaving a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 690

Step 3:
690 goes into 452 0 times with a remainder of 452.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 452 after subtracting 0 from 452.
Fetch the next digit (8) from the dividend, attach it to 452 and continue: 4528 / 690

Advancing to step 4:
When dividing 4528 by 690, we get 6 with a remainder of 388.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 388 after subtracting 4140 from 4528.
Include the next digit (6) from the dividend after 388, then repeat: 3886 / 690

Step 5:
If we divide 3886 by 690, we get 5 and a remainder of 436.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 3450 away from 3886, we end up with 436.
Bring next digit (3) of the dividend behind the 436 and repeat the process: 4363 / 690

Advancing to step 6:
690 goes into 4363 6 times with a remainder of 223.
The next digit of our result is 6. 
Result so far: 656.0
Deduct 4140 from 4363 and we're left with 223.
Fetch the next digit (0) from the dividend, attach it to 223 and continue: 2230 / 690

Advancing to step 7:
When dividing 2230 by 690, we get 3 with a remainder of 160.
Put 3 as the next digit of the answer. 
Result so far: 6563.0
The remainder is 160 after subtracting 2070 from 2230.
Bring next digit (1) of the dividend behind the 160 and repeat the process: 1601 / 690

Moving on to step 8:
The number 690 fits into 1601 2 times, leaving a remainder of 221.
Use 2 as the next digit of our solution. 
Result so far: 65632.0
The remainder is 221 after subtracting 1380 from 1601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Going ahead to step 9:
If we divide 2210 by 690, we get 3 and a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 65632.3
Deduct 2070 from 2210 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
1400 divided by 690 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 65632.32
The remainder is 20 after subtracting 1380 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 690 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 65632.32
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
690 can be fit into 2000 2 times, resulting in a remainder of 620.
Put 2 as the next digit of the answer. 
Result so far: 65632.3202
If we subtract 1380 from 2000, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 13:
690 goes into 6200 8 times with a remainder of 680.
Use 8 as the next digit of our solution. 
Result so far: 65632.32028
If we subtract 5520 from 6200, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 14:
690 goes into 6800 9 times with a remainder of 590.
The next digit of our result is 9. 
Result so far: 65632.320289
If we take 6210 away from 6800, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 15:
If we divide 5900 by 690, we get 8 and a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 65632.3202898
Deduct 5520 from 5900 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 16:
690 can be fit into 3800 5 times, resulting in a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 65632.32028985
The remainder is 350 after subtracting 3450 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

After the division, we end up with 65632.32028985 and a remainder of 3.5e-07.
