81335028 divided by 972 
The aim is to understand the frequency of 972 in 81335028.

Advancing to step 1:
If we divide 8 by 972, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 972

On to step 2:
If we divide 81 by 972, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 972

Going ahead to step 3:
972 can be fit into 813 0 times, resulting in a remainder of 813.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 813 leaves us with 813.
Include the next digit (3) from the dividend after 813, then repeat: 8133 / 972

Let's proceed to step 4:
The number 972 fits into 8133 8 times, leaving a remainder of 357.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 7776 away from 8133, we end up with 357.
Take the next digit (5) from the dividend and append it to 357, then repeat: 3575 / 972

Going ahead to step 5:
3575 divided by 972 is 3 with a remainder of 659.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Subtracting 2916 from 3575 leaves us with 659.
Append the next digit (0) from the dividend to 659 and continue with: 6590 / 972

Step 6:
972 goes into 6590 6 times with a remainder of 758.
Use 6 as the next digit of our solution. 
Result so far: 836.0
Subtract 5832 from 6590 to get 758.
Take the next digit (2) from the dividend and append it to 758, then repeat: 7582 / 972

Going ahead to step 7:
The number 972 fits into 7582 7 times, leaving a remainder of 778.
Put 7 as the next digit of the answer. 
Result so far: 8367.0
Deduct 6804 from 7582 and we're left with 778.
Fetch the next digit (8) from the dividend, attach it to 778 and continue: 7788 / 972

Let's proceed to step 8:
If we divide 7788 by 972, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 83678.0
If we subtract 7776 from 7788, 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.

Step 9:
If we divide 120 by 972, we get 0 and a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 83678.0
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
1200 divided by 972 is 1 with a remainder of 228.
Write down 1 as next digit of the result. 
Result so far: 83678.01
If we subtract 972 from 1200, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
The number 972 fits into 2280 2 times, leaving a remainder of 336.
Use 2 as the next digit of our solution. 
Result so far: 83678.012
Subtract 1944 from 2280 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 12:
3360 divided by 972 is 3 with a remainder of 444.
The number 3 becomes the next digit in our result. 
Result so far: 83678.0123
Subtracting 2916 from 3360 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 13:
When dividing 4440 by 972, we get 4 with a remainder of 552.
Record the quotient 4 as the next digit in the result. 
Result so far: 83678.01234
Subtracting 3888 from 4440 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 14:
972 goes into 5520 5 times with a remainder of 660.
Write down 5 as next digit of the result. 
Result so far: 83678.012345
If we take 4860 away from 5520, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 15:
972 can be fit into 6600 6 times, resulting in a remainder of 768.
The number 6 becomes the next digit in our result. 
Result so far: 83678.0123456
Subtract 5832 from 6600 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Step 16:
The number 972 fits into 7680 7 times, leaving a remainder of 876.
The number 7 becomes the next digit in our result. 
Result so far: 83678.01234567
Deduct 6804 from 7680 and we're left with 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

The final result is 83678.01234567 with a remainder of 8.76e-07.
