37629485 divided by 661 
The aim is to understand the frequency of 661 in 37629485.

Going ahead to step 1:
3 divided by 661 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 661

Going ahead to step 2:
37 divided by 661 is 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 661

On to step 3:
If we divide 376 by 661, we get 0 and a remainder of 376.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 376 and we're left with 376.
Fetch the next digit (2) from the dividend, attach it to 376 and continue: 3762 / 661

Step 4:
3762 divided by 661 is 5 with a remainder of 457.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 3305 from 3762 and we're left with 457.
Take the next digit (9) from the dividend and append it to 457, then repeat: 4579 / 661

Step 5:
661 goes into 4579 6 times with a remainder of 613.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtract 3966 from 4579 to get 613.
Fetch the next digit (4) from the dividend, attach it to 613 and continue: 6134 / 661

Advancing to step 6:
661 can be fit into 6134 9 times, resulting in a remainder of 185.
The next digit of our result is 9. 
Result so far: 569.0
Deduct 5949 from 6134 and we're left with 185.
Take the next digit (8) from the dividend and append it to 185, then repeat: 1858 / 661

On to step 7:
661 can be fit into 1858 2 times, resulting in a remainder of 536.
Record the quotient 2 as the next digit in the result. 
Result so far: 5692.0
Subtracting 1322 from 1858 leaves us with 536.
Include the next digit (5) from the dividend after 536, then repeat: 5365 / 661

Let's proceed to step 8:
661 goes into 5365 8 times with a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 56928.0
The remainder is 77 after subtracting 5288 from 5365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 9:
If we divide 770 by 661, we get 1 and a remainder of 109.
Use 1 as the next digit of our solution. 
Result so far: 56928.1
If we subtract 661 from 770, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 10:
661 can be fit into 1090 1 times, resulting in a remainder of 429.
Put 1 as the next digit of the answer. 
Result so far: 56928.11
If we subtract 661 from 1090, we get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

The final result is 56928.11 with a remainder of 0.429.
