49389379 ÷ 671 
The aim is to understand the frequency of 671 in 49389379.

Advancing to step 1:
When dividing 4 by 671, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 671

Advancing to step 2:
When dividing 49 by 671, we get 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Append the next digit (3) from the dividend to 49 and continue with: 493 / 671

Moving on to step 3:
671 goes into 493 0 times with a remainder of 493.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 493 after subtracting 0 from 493.
Grab the next digit (8) from the dividend, add it to 493, then carry on: 4938 / 671

Step 4:
When dividing 4938 by 671, we get 7 with a remainder of 241.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4697 from 4938, we get 241.
Grab the next digit (9) from the dividend, add it to 241, then carry on: 2419 / 671

Moving on to step 5:
671 goes into 2419 3 times with a remainder of 406.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we take 2013 away from 2419, we end up with 406.
Bring next digit (3) of the dividend behind the 406 and repeat the process: 4063 / 671

Let's proceed to step 6:
671 can be fit into 4063 6 times, resulting in a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 736.0
The remainder is 37 after subtracting 4026 from 4063.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 671

Let's proceed to step 7:
The number 671 fits into 377 0 times, leaving a remainder of 377.
Write down 0 as next digit of the result. 
Result so far: 7360.0
Subtracting 0 from 377 leaves us with 377.
Take the next digit (9) from the dividend and append it to 377, then repeat: 3779 / 671

On to step 8:
3779 divided by 671 is 5 with a remainder of 424.
Record the quotient 5 as the next digit in the result. 
Result so far: 73605.0
If we take 3355 away from 3779, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 9:
671 can be fit into 4240 6 times, resulting in a remainder of 214.
The number 6 becomes the next digit in our result. 
Result so far: 73605.6
If we take 4026 away from 4240, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 10:
671 can be fit into 2140 3 times, resulting in a remainder of 127.
The number 3 becomes the next digit in our result. 
Result so far: 73605.63
Subtracting 2013 from 2140 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 11:
1270 divided by 671 is 1 with a remainder of 599.
Write down 1 as next digit of the result. 
Result so far: 73605.631
The remainder is 599 after subtracting 671 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Let's proceed to step 12:
When dividing 5990 by 671, we get 8 with a remainder of 622.
Write down 8 as next digit of the result. 
Result so far: 73605.6318
Subtract 5368 from 5990 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Step 13:
671 goes into 6220 9 times with a remainder of 181.
Write down 9 as next digit of the result. 
Result so far: 73605.63189
Subtract 6039 from 6220 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 14:
When dividing 1810 by 671, we get 2 with a remainder of 468.
Write down 2 as next digit of the result. 
Result so far: 73605.631892
Deduct 1342 from 1810 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 15:
The number 671 fits into 4680 6 times, leaving a remainder of 654.
Write down 6 as next digit of the result. 
Result so far: 73605.6318926
The remainder is 654 after subtracting 4026 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Step 16:
6540 divided by 671 is 9 with a remainder of 501.
Record the quotient 9 as the next digit in the result. 
Result so far: 73605.63189269
Subtract 6039 from 6540 to get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

After the division, we end up with 73605.63189269 and a remainder of 5.01e-07.
