We divide 370986 by 91
The aim is to understand the frequency of 91 in 370986.

Going ahead to step 1:
The number 91 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 91

Advancing to step 2:
91 goes into 37 0 times with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 91

On to step 3:
370 divided by 91 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 364 from 370 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 91

Step 4:
When dividing 69 by 91, we get 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 69 to get 69.
Take the next digit (8) from the dividend and append it to 69, then repeat: 698 / 91

On to step 5:
The number 91 fits into 698 7 times, leaving a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
Subtracting 637 from 698 leaves us with 61.
Fetch the next digit (6) from the dividend, attach it to 61 and continue: 616 / 91

Step 6:
91 goes into 616 6 times with a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 4076.0
The remainder is 70 after subtracting 546 from 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
If we divide 700 by 91, we get 7 and a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 4076.7
If we take 637 away from 700, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 8:
If we divide 630 by 91, we get 6 and a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 4076.76
Deduct 546 from 630 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
When dividing 840 by 91, we get 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 4076.769
Subtract 819 from 840 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
If we divide 210 by 91, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 4076.7692
If we subtract 182 from 210, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
280 divided by 91 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 4076.76923
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
The number 91 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 4076.76923
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
700 divided by 91 is 7 with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 4076.7692307
If we take 637 away from 700, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 14:
If we divide 630 by 91, we get 6 and a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 4076.76923076
If we subtract 546 from 630, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The quotient of the division is 4076.76923076, and the remainder is 8.4e-08.
