We're dividing 90979184 by 764 
The aim is to understand the frequency of 764 in 90979184.

Step 1:
If we divide 9 by 764, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 764

Step 2:
90 divided by 764 is 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Append the next digit (9) from the dividend to 90 and continue with: 909 / 764

Moving on to step 3:
764 can be fit into 909 1 times, resulting in a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 764 from 909 and we're left with 145.
Include the next digit (7) from the dividend after 145, then repeat: 1457 / 764

On to step 4:
764 can be fit into 1457 1 times, resulting in a remainder of 693.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 693 after subtracting 764 from 1457.
Grab the next digit (9) from the dividend, add it to 693, then carry on: 6939 / 764

Advancing to step 5:
When dividing 6939 by 764, we get 9 with a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Subtract 6876 from 6939 to get 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 764

Step 6:
631 divided by 764 is 0 with a remainder of 631.
Put 0 as the next digit of the answer. 
Result so far: 1190.0
The remainder is 631 after subtracting 0 from 631.
Take the next digit (8) from the dividend and append it to 631, then repeat: 6318 / 764

On to step 7:
If we divide 6318 by 764, we get 8 and a remainder of 206.
Use 8 as the next digit of our solution. 
Result so far: 11908.0
The remainder is 206 after subtracting 6112 from 6318.
Take the next digit (4) from the dividend and append it to 206, then repeat: 2064 / 764

Moving on to step 8:
764 can be fit into 2064 2 times, resulting in a remainder of 536.
Record the quotient 2 as the next digit in the result. 
Result so far: 119082.0
If we subtract 1528 from 2064, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 9:
When dividing 5360 by 764, we get 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 119082.7
If we subtract 5348 from 5360, 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.

Going ahead to step 10:
764 can be fit into 120 0 times, resulting in a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 119082.7
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
764 goes into 1200 1 times with a remainder of 436.
The next digit of our result is 1. 
Result so far: 119082.701
Subtracting 764 from 1200 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 12:
764 can be fit into 4360 5 times, resulting in a remainder of 540.
The next digit of our result is 5. 
Result so far: 119082.7015
Subtract 3820 from 4360 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 13:
5400 divided by 764 is 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 119082.70157
Subtract 5348 from 5400 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
The number 764 fits into 520 0 times, leaving a remainder of 520.
The next digit of our result is 0. 
Result so far: 119082.70157
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 15:
764 can be fit into 5200 6 times, resulting in a remainder of 616.
The number 6 becomes the next digit in our result. 
Result so far: 119082.7015706
If we take 4584 away from 5200, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 16:
When dividing 6160 by 764, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 119082.70157068
Deduct 6112 from 6160 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 119082.70157068 and a remainder of 4.8e-08.
