We're dividing 91354893 by 971 
The aim is to understand the frequency of 971 in 91354893.

Step 1:
The number 971 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 971

Moving on to step 2:
When dividing 91 by 971, we get 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Append the next digit (3) from the dividend to 91 and continue with: 913 / 971

Going ahead to step 3:
The number 971 fits into 913 0 times, leaving a remainder of 913.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 913 after subtracting 0 from 913.
Bring next digit (5) of the dividend behind the 913 and repeat the process: 9135 / 971

Let's proceed to step 4:
If we divide 9135 by 971, we get 9 and a remainder of 396.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 396 after subtracting 8739 from 9135.
Bring next digit (4) of the dividend behind the 396 and repeat the process: 3964 / 971

Let's proceed to step 5:
If we divide 3964 by 971, we get 4 and a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Deduct 3884 from 3964 and we're left with 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 971

On to step 6:
When dividing 808 by 971, we get 0 with a remainder of 808.
Write down 0 as next digit of the result. 
Result so far: 940.0
If we take 0 away from 808, we end up with 808.
Take the next digit (9) from the dividend and append it to 808, then repeat: 8089 / 971

Advancing to step 7:
The number 971 fits into 8089 8 times, leaving a remainder of 321.
Write down 8 as next digit of the result. 
Result so far: 9408.0
Subtracting 7768 from 8089 leaves us with 321.
Include the next digit (3) from the dividend after 321, then repeat: 3213 / 971

Let's proceed to step 8:
When dividing 3213 by 971, we get 3 with a remainder of 300.
Write down 3 as next digit of the result. 
Result so far: 94083.0
Deduct 2913 from 3213 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 9:
The number 971 fits into 3000 3 times, leaving a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 94083.3
Subtract 2913 from 3000 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 10:
When dividing 870 by 971, we get 0 with a remainder of 870.
Put 0 as the next digit of the answer. 
Result so far: 94083.3
Subtract 0 from 870 to get 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

On to step 11:
971 can be fit into 8700 8 times, resulting in a remainder of 932.
The next digit of our result is 8. 
Result so far: 94083.308
If we subtract 7768 from 8700, we get 932.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9320, and continue the process.

Let's proceed to step 12:
9320 divided by 971 is 9 with a remainder of 581.
The next digit of our result is 9. 
Result so far: 94083.3089
If we subtract 8739 from 9320, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Let's proceed to step 13:
971 can be fit into 5810 5 times, resulting in a remainder of 955.
The number 5 becomes the next digit in our result. 
Result so far: 94083.30895
Subtracting 4855 from 5810 leaves us with 955.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9550, and continue the process.

Advancing to step 14:
971 goes into 9550 9 times with a remainder of 811.
Record the quotient 9 as the next digit in the result. 
Result so far: 94083.308959
If we take 8739 away from 9550, we end up with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Advancing to step 15:
If we divide 8110 by 971, we get 8 and a remainder of 342.
The number 8 becomes the next digit in our result. 
Result so far: 94083.3089598
Subtracting 7768 from 8110 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 16:
971 goes into 3420 3 times with a remainder of 507.
Put 3 as the next digit of the answer. 
Result so far: 94083.30895983
If we take 2913 away from 3420, we end up with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

The quotient of the division is 94083.30895983, and the remainder is 5.07e-07.
