Let's divide 40154524 by 671
The aim is to understand the frequency of 671 in 40154524.

Advancing to step 1:
When dividing 4 by 671, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 671

Moving on to step 2:
40 divided by 671 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 671

Let's proceed to step 3:
401 divided by 671 is 0 with a remainder of 401.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 401 to get 401.
Grab the next digit (5) from the dividend, add it to 401, then carry on: 4015 / 671

On to step 4:
If we divide 4015 by 671, we get 5 and a remainder of 660.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 3355 from 4015 to get 660.
Fetch the next digit (4) from the dividend, attach it to 660 and continue: 6604 / 671

Advancing to step 5:
The number 671 fits into 6604 9 times, leaving a remainder of 565.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtract 6039 from 6604 to get 565.
Append the next digit (5) from the dividend to 565 and continue with: 5655 / 671

Let's proceed to step 6:
671 goes into 5655 8 times with a remainder of 287.
Record the quotient 8 as the next digit in the result. 
Result so far: 598.0
If we take 5368 away from 5655, we end up with 287.
Fetch the next digit (2) from the dividend, attach it to 287 and continue: 2872 / 671

Moving on to step 7:
The number 671 fits into 2872 4 times, leaving a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 5984.0
If we subtract 2684 from 2872, we get 188.
Grab the next digit (4) from the dividend, add it to 188, then carry on: 1884 / 671

Going ahead to step 8:
1884 divided by 671 is 2 with a remainder of 542.
Put 2 as the next digit of the answer. 
Result so far: 59842.0
If we subtract 1342 from 1884, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

On to step 9:
The number 671 fits into 5420 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 59842.8
Subtract 5368 from 5420 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
If we divide 520 by 671, we get 0 and a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 59842.8
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 11:
If we divide 5200 by 671, we get 7 and a remainder of 503.
Record the quotient 7 as the next digit in the result. 
Result so far: 59842.807
If we subtract 4697 from 5200, we get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Step 12:
When dividing 5030 by 671, we get 7 with a remainder of 333.
The number 7 becomes the next digit in our result. 
Result so far: 59842.8077
Subtract 4697 from 5030 to get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

The final outcome is 59842.8077, with a leftover of 0.00333.
