We divide 72181637 by 667
The aim is to understand the frequency of 667 in 72181637.

Going ahead to step 1:
7 divided by 667 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 667

On to step 2:
667 can be fit into 72 0 times, resulting in a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 667

Advancing to step 3:
The number 667 fits into 721 1 times, leaving a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 667 from 721 leaves us with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 667

Let's proceed to step 4:
667 goes into 548 0 times with a remainder of 548.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 548 and we're left with 548.
Bring next digit (1) of the dividend behind the 548 and repeat the process: 5481 / 667

Moving on to step 5:
The number 667 fits into 5481 8 times, leaving a remainder of 145.
The next digit of our result is 8. 
Result so far: 108.0
The remainder is 145 after subtracting 5336 from 5481.
Grab the next digit (6) from the dividend, add it to 145, then carry on: 1456 / 667

Let's proceed to step 6:
If we divide 1456 by 667, we get 2 and a remainder of 122.
Record the quotient 2 as the next digit in the result. 
Result so far: 1082.0
Subtract 1334 from 1456 to get 122.
Grab the next digit (3) from the dividend, add it to 122, then carry on: 1223 / 667

Let's proceed to step 7:
1223 divided by 667 is 1 with a remainder of 556.
The number 1 becomes the next digit in our result. 
Result so far: 10821.0
If we take 667 away from 1223, we end up with 556.
Take the next digit (7) from the dividend and append it to 556, then repeat: 5567 / 667

Moving on to step 8:
667 goes into 5567 8 times with a remainder of 231.
Put 8 as the next digit of the answer. 
Result so far: 108218.0
If we subtract 5336 from 5567, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 9:
2310 divided by 667 is 3 with a remainder of 309.
Write down 3 as next digit of the result. 
Result so far: 108218.3
Subtracting 2001 from 2310 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 10:
667 goes into 3090 4 times with a remainder of 422.
Write down 4 as next digit of the result. 
Result so far: 108218.34
Deduct 2668 from 3090 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 11:
667 can be fit into 4220 6 times, resulting in a remainder of 218.
Write down 6 as next digit of the result. 
Result so far: 108218.346
The remainder is 218 after subtracting 4002 from 4220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 12:
When dividing 2180 by 667, we get 3 with a remainder of 179.
The number 3 becomes the next digit in our result. 
Result so far: 108218.3463
Subtracting 2001 from 2180 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 13:
1790 divided by 667 is 2 with a remainder of 456.
Put 2 as the next digit of the answer. 
Result so far: 108218.34632
If we take 1334 away from 1790, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 14:
If we divide 4560 by 667, we get 6 and a remainder of 558.
Use 6 as the next digit of our solution. 
Result so far: 108218.346326
If we take 4002 away from 4560, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Let's proceed to step 15:
667 goes into 5580 8 times with a remainder of 244.
Use 8 as the next digit of our solution. 
Result so far: 108218.3463268
If we take 5336 away from 5580, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 16:
2440 divided by 667 is 3 with a remainder of 439.
The next digit of our result is 3. 
Result so far: 108218.34632683
The remainder is 439 after subtracting 2001 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

The final outcome is 108218.34632683, with a leftover of 4.39e-07.
