We look at the division of 37674561 by 671 
The aim is to understand the frequency of 671 in 37674561.

Advancing to step 1:
When dividing 3 by 671, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 671

Advancing to step 2:
If we divide 37 by 671, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 671

Going ahead to step 3:
671 goes into 376 0 times with a remainder of 376.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 376 after subtracting 0 from 376.
Bring next digit (7) of the dividend behind the 376 and repeat the process: 3767 / 671

Advancing to step 4:
671 can be fit into 3767 5 times, resulting in a remainder of 412.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 412 after subtracting 3355 from 3767.
Bring next digit (4) of the dividend behind the 412 and repeat the process: 4124 / 671

Advancing to step 5:
If we divide 4124 by 671, we get 6 and a remainder of 98.
Use 6 as the next digit of our solution. 
Result so far: 56.0
If we subtract 4026 from 4124, we get 98.
Bring next digit (5) of the dividend behind the 98 and repeat the process: 985 / 671

Moving on to step 6:
If we divide 985 by 671, we get 1 and a remainder of 314.
Use 1 as the next digit of our solution. 
Result so far: 561.0
The remainder is 314 after subtracting 671 from 985.
Append the next digit (6) from the dividend to 314 and continue with: 3146 / 671

Advancing to step 7:
The number 671 fits into 3146 4 times, leaving a remainder of 462.
Record the quotient 4 as the next digit in the result. 
Result so far: 5614.0
If we take 2684 away from 3146, we end up with 462.
Append the next digit (1) from the dividend to 462 and continue with: 4621 / 671

Going ahead to step 8:
When dividing 4621 by 671, we get 6 with a remainder of 595.
Write down 6 as next digit of the result. 
Result so far: 56146.0
The remainder is 595 after subtracting 4026 from 4621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 9:
671 can be fit into 5950 8 times, resulting in a remainder of 582.
Put 8 as the next digit of the answer. 
Result so far: 56146.8
Subtracting 5368 from 5950 leaves us with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Step 10:
671 can be fit into 5820 8 times, resulting in a remainder of 452.
Put 8 as the next digit of the answer. 
Result so far: 56146.88
Subtract 5368 from 5820 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

In conclusion, the division gives 56146.88 with a balance of 0.452.
