52186939 ÷ 667 
The aim is to understand the frequency of 667 in 52186939.

On to step 1:
667 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 667

Let's proceed to step 2:
52 divided by 667 is 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 667

Step 3:
521 divided by 667 is 0 with a remainder of 521.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 521 to get 521.
Grab the next digit (8) from the dividend, add it to 521, then carry on: 5218 / 667

Let's proceed to step 4:
667 can be fit into 5218 7 times, resulting in a remainder of 549.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 4669 from 5218, we get 549.
Bring next digit (6) of the dividend behind the 549 and repeat the process: 5496 / 667

Step 5:
When dividing 5496 by 667, we get 8 with a remainder of 160.
The next digit of our result is 8. 
Result so far: 78.0
Subtracting 5336 from 5496 leaves us with 160.
Include the next digit (9) from the dividend after 160, then repeat: 1609 / 667

Step 6:
The number 667 fits into 1609 2 times, leaving a remainder of 275.
Record the quotient 2 as the next digit in the result. 
Result so far: 782.0
Deduct 1334 from 1609 and we're left with 275.
Grab the next digit (3) from the dividend, add it to 275, then carry on: 2753 / 667

Advancing to step 7:
667 can be fit into 2753 4 times, resulting in a remainder of 85.
The number 4 becomes the next digit in our result. 
Result so far: 7824.0
If we take 2668 away from 2753, we end up with 85.
Include the next digit (9) from the dividend after 85, then repeat: 859 / 667

On to step 8:
667 goes into 859 1 times with a remainder of 192.
The next digit of our result is 1. 
Result so far: 78241.0
If we subtract 667 from 859, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 9:
1920 divided by 667 is 2 with a remainder of 586.
The number 2 becomes the next digit in our result. 
Result so far: 78241.2
Subtract 1334 from 1920 to get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Let's proceed to step 10:
If we divide 5860 by 667, we get 8 and a remainder of 524.
Record the quotient 8 as the next digit in the result. 
Result so far: 78241.28
Subtract 5336 from 5860 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 11:
667 can be fit into 5240 7 times, resulting in a remainder of 571.
The number 7 becomes the next digit in our result. 
Result so far: 78241.287
If we subtract 4669 from 5240, we get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Moving on to step 12:
When dividing 5710 by 667, we get 8 with a remainder of 374.
The next digit of our result is 8. 
Result so far: 78241.2878
If we subtract 5336 from 5710, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 13:
The number 667 fits into 3740 5 times, leaving a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 78241.28785
The remainder is 405 after subtracting 3335 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 14:
667 goes into 4050 6 times with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 78241.287856
If we take 4002 away from 4050, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 15:
The number 667 fits into 480 0 times, leaving a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 78241.287856
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 16:
The number 667 fits into 4800 7 times, leaving a remainder of 131.
Write down 7 as next digit of the result. 
Result so far: 78241.28785607
Subtracting 4669 from 4800 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

In conclusion, the division gives 78241.28785607 with a balance of 1.31e-07.
