681465 divided by 91 
The aim is to understand the frequency of 91 in 681465.

Moving on to step 1:
91 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 91

Step 2:
When dividing 68 by 91, we get 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Bring next digit (1) of the dividend behind the 68 and repeat the process: 681 / 91

Let's proceed to step 3:
If we divide 681 by 91, we get 7 and a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 637 from 681 and we're left with 44.
Fetch the next digit (4) from the dividend, attach it to 44 and continue: 444 / 91

Step 4:
444 divided by 91 is 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 74.0
The remainder is 80 after subtracting 364 from 444.
Fetch the next digit (6) from the dividend, attach it to 80 and continue: 806 / 91

Step 5:
When dividing 806 by 91, we get 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 748.0
Subtract 728 from 806 to get 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 91

On to step 6:
91 can be fit into 785 8 times, resulting in a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 7488.0
If we subtract 728 from 785, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 7:
570 divided by 91 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 7488.6
Deduct 546 from 570 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
The number 91 fits into 240 2 times, leaving a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 7488.62
Subtracting 182 from 240 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
91 goes into 580 6 times with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 7488.626
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
When dividing 340 by 91, we get 3 with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 7488.6263
Subtracting 273 from 340 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
91 goes into 670 7 times with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 7488.62637
Subtracting 637 from 670 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
When dividing 330 by 91, we get 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 7488.626373
If we take 273 away from 330, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
570 divided by 91 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 7488.6263736
The remainder is 24 after subtracting 546 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
91 goes into 240 2 times with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 7488.62637362
The remainder is 58 after subtracting 182 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 7488.62637362, and the remainder is 5.8e-08.
