We look at the division of 46003905 by 660 
The aim is to understand the frequency of 660 in 46003905.

Moving on to step 1:
660 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 660

Advancing to step 2:
When dividing 46 by 660, we get 0 with a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 46 and we're left with 46.
Take the next digit (0) from the dividend and append it to 46, then repeat: 460 / 660

Step 3:
660 can be fit into 460 0 times, resulting in a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 460 to get 460.
Take the next digit (0) from the dividend and append it to 460, then repeat: 4600 / 660

On to step 4:
660 can be fit into 4600 6 times, resulting in a remainder of 640.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 3960 from 4600 and we're left with 640.
Include the next digit (3) from the dividend after 640, then repeat: 6403 / 660

Step 5:
660 goes into 6403 9 times with a remainder of 463.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Deduct 5940 from 6403 and we're left with 463.
Take the next digit (9) from the dividend and append it to 463, then repeat: 4639 / 660

Let's proceed to step 6:
If we divide 4639 by 660, we get 7 and a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 697.0
If we take 4620 away from 4639, we end up with 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 660

Let's proceed to step 7:
When dividing 190 by 660, we get 0 with a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 6970.0
If we take 0 away from 190, we end up with 190.
Append the next digit (5) from the dividend to 190 and continue with: 1905 / 660

Let's proceed to step 8:
660 goes into 1905 2 times with a remainder of 585.
Put 2 as the next digit of the answer. 
Result so far: 69702.0
Subtracting 1320 from 1905 leaves us with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 9:
When dividing 5850 by 660, we get 8 with a remainder of 570.
Put 8 as the next digit of the answer. 
Result so far: 69702.8
If we take 5280 away from 5850, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 10:
When dividing 5700 by 660, we get 8 with a remainder of 420.
Record the quotient 8 as the next digit in the result. 
Result so far: 69702.88
If we take 5280 away from 5700, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

In conclusion, the division gives 69702.88 with a balance of 0.42.
