67186637 divided by 731 
The aim is to understand the frequency of 731 in 67186637.

On to step 1:
When dividing 6 by 731, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 731

On to step 2:
The number 731 fits into 67 0 times, leaving a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Take the next digit (1) from the dividend and append it to 67, then repeat: 671 / 731

Moving on to step 3:
731 goes into 671 0 times with a remainder of 671.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 671 leaves us with 671.
Include the next digit (8) from the dividend after 671, then repeat: 6718 / 731

Moving on to step 4:
If we divide 6718 by 731, we get 9 and a remainder of 139.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 139 after subtracting 6579 from 6718.
Include the next digit (6) from the dividend after 139, then repeat: 1396 / 731

Moving on to step 5:
1396 divided by 731 is 1 with a remainder of 665.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Deduct 731 from 1396 and we're left with 665.
Bring next digit (6) of the dividend behind the 665 and repeat the process: 6656 / 731

Moving on to step 6:
731 goes into 6656 9 times with a remainder of 77.
Write down 9 as next digit of the result. 
Result so far: 919.0
If we subtract 6579 from 6656, we get 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 731

Step 7:
The number 731 fits into 773 1 times, leaving a remainder of 42.
The next digit of our result is 1. 
Result so far: 9191.0
If we subtract 731 from 773, we get 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 731

Let's proceed to step 8:
731 can be fit into 427 0 times, resulting in a remainder of 427.
Write down 0 as next digit of the result. 
Result so far: 91910.0
Deduct 0 from 427 and we're left with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Going ahead to step 9:
When dividing 4270 by 731, we get 5 with a remainder of 615.
Put 5 as the next digit of the answer. 
Result so far: 91910.5
If we take 3655 away from 4270, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Let's proceed to step 10:
If we divide 6150 by 731, we get 8 and a remainder of 302.
Put 8 as the next digit of the answer. 
Result so far: 91910.58
Subtracting 5848 from 6150 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 11:
3020 divided by 731 is 4 with a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 91910.584
If we subtract 2924 from 3020, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
When dividing 960 by 731, we get 1 with a remainder of 229.
Write down 1 as next digit of the result. 
Result so far: 91910.5841
If we subtract 731 from 960, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Moving on to step 13:
731 can be fit into 2290 3 times, resulting in a remainder of 97.
The number 3 becomes the next digit in our result. 
Result so far: 91910.58413
Subtract 2193 from 2290 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 14:
When dividing 970 by 731, we get 1 with a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 91910.584131
Subtracting 731 from 970 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 15:
The number 731 fits into 2390 3 times, leaving a remainder of 197.
The number 3 becomes the next digit in our result. 
Result so far: 91910.5841313
Subtracting 2193 from 2390 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 16:
1970 divided by 731 is 2 with a remainder of 508.
The number 2 becomes the next digit in our result. 
Result so far: 91910.58413132
The remainder is 508 after subtracting 1462 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

The quotient of the division is 91910.58413132, and the remainder is 5.08e-07.
