694136 divided by 91 
The aim is to understand the frequency of 91 in 694136.

Advancing to step 1:
6 divided by 91 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 91

Going ahead to step 2:
69 divided by 91 is 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (4) from the dividend to 69 and continue with: 694 / 91

Advancing to step 3:
91 goes into 694 7 times with a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 637 from 694, we get 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 91

Going ahead to step 4:
If we divide 571 by 91, we get 6 and a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
The remainder is 25 after subtracting 546 from 571.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 91

Advancing to step 5:
The number 91 fits into 253 2 times, leaving a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 762.0
Subtract 182 from 253 to get 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 91

Let's proceed to step 6:
91 can be fit into 716 7 times, resulting in a remainder of 79.
Put 7 as the next digit of the answer. 
Result so far: 7627.0
If we subtract 637 from 716, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 7:
91 can be fit into 790 8 times, resulting in a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 7627.8
Subtract 728 from 790 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
620 divided by 91 is 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 7627.86
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
When dividing 740 by 91, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 7627.868
If we subtract 728 from 740, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
If we divide 120 by 91, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 7627.8681
If we subtract 91 from 120, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
91 can be fit into 290 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 7627.86813
Subtracting 273 from 290 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
When dividing 170 by 91, we get 1 with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 7627.868131
If we take 91 away from 170, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 13:
When dividing 790 by 91, we get 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 7627.8681318
Subtract 728 from 790 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 14:
If we divide 620 by 91, we get 6 and a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 7627.86813186
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final outcome is 7627.86813186, with a leftover of 7.4e-08.
