We're dividing 37450637 by 666 
The aim is to understand the frequency of 666 in 37450637.

Moving on to step 1:
3 divided by 666 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 666

Advancing to step 2:
666 can be fit into 37 0 times, resulting in a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 666

Advancing to step 3:
666 can be fit into 374 0 times, resulting in a remainder of 374.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 374 leaves us with 374.
Fetch the next digit (5) from the dividend, attach it to 374 and continue: 3745 / 666

Let's proceed to step 4:
666 goes into 3745 5 times with a remainder of 415.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 3330 from 3745 and we're left with 415.
Include the next digit (0) from the dividend after 415, then repeat: 4150 / 666

On to step 5:
The number 666 fits into 4150 6 times, leaving a remainder of 154.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 3996 from 4150, we get 154.
Take the next digit (6) from the dividend and append it to 154, then repeat: 1546 / 666

Moving on to step 6:
If we divide 1546 by 666, we get 2 and a remainder of 214.
Use 2 as the next digit of our solution. 
Result so far: 562.0
If we take 1332 away from 1546, we end up with 214.
Append the next digit (3) from the dividend to 214 and continue with: 2143 / 666

Let's proceed to step 7:
666 can be fit into 2143 3 times, resulting in a remainder of 145.
Write down 3 as next digit of the result. 
Result so far: 5623.0
If we subtract 1998 from 2143, we get 145.
Include the next digit (7) from the dividend after 145, then repeat: 1457 / 666

Moving on to step 8:
If we divide 1457 by 666, we get 2 and a remainder of 125.
Record the quotient 2 as the next digit in the result. 
Result so far: 56232.0
Subtracting 1332 from 1457 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 9:
If we divide 1250 by 666, we get 1 and a remainder of 584.
Use 1 as the next digit of our solution. 
Result so far: 56232.1
If we take 666 away from 1250, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 10:
5840 divided by 666 is 8 with a remainder of 512.
The next digit of our result is 8. 
Result so far: 56232.18
Subtracting 5328 from 5840 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 11:
5120 divided by 666 is 7 with a remainder of 458.
The number 7 becomes the next digit in our result. 
Result so far: 56232.187
If we subtract 4662 from 5120, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 12:
The number 666 fits into 4580 6 times, leaving a remainder of 584.
The number 6 becomes the next digit in our result. 
Result so far: 56232.1876
If we take 3996 away from 4580, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Going ahead to step 13:
666 can be fit into 5840 8 times, resulting in a remainder of 512.
Record the quotient 8 as the next digit in the result. 
Result so far: 56232.18768
If we subtract 5328 from 5840, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 14:
666 goes into 5120 7 times with a remainder of 458.
The number 7 becomes the next digit in our result. 
Result so far: 56232.187687
If we take 4662 away from 5120, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 15:
If we divide 4580 by 666, we get 6 and a remainder of 584.
Use 6 as the next digit of our solution. 
Result so far: 56232.1876876
If we take 3996 away from 4580, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Advancing to step 16:
The number 666 fits into 5840 8 times, leaving a remainder of 512.
Use 8 as the next digit of our solution. 
Result so far: 56232.18768768
If we subtract 5328 from 5840, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Our division results in 56232.18768768 with a remaining 5.12e-07.
