Let's divide 80375889 by 974
The aim is to understand the frequency of 974 in 80375889.

Step 1:
974 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 974

On to step 2:
The number 974 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 974

Let's proceed to step 3:
When dividing 803 by 974, we get 0 with a remainder of 803.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 803 after subtracting 0 from 803.
Include the next digit (7) from the dividend after 803, then repeat: 8037 / 974

Advancing to step 4:
974 can be fit into 8037 8 times, resulting in a remainder of 245.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7792 from 8037 to get 245.
Fetch the next digit (5) from the dividend, attach it to 245 and continue: 2455 / 974

Going ahead to step 5:
974 can be fit into 2455 2 times, resulting in a remainder of 507.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtract 1948 from 2455 to get 507.
Append the next digit (8) from the dividend to 507 and continue with: 5078 / 974

Let's proceed to step 6:
The number 974 fits into 5078 5 times, leaving a remainder of 208.
Record the quotient 5 as the next digit in the result. 
Result so far: 825.0
Subtracting 4870 from 5078 leaves us with 208.
Fetch the next digit (8) from the dividend, attach it to 208 and continue: 2088 / 974

Let's proceed to step 7:
When dividing 2088 by 974, we get 2 with a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 8252.0
Subtract 1948 from 2088 to get 140.
Append the next digit (9) from the dividend to 140 and continue with: 1409 / 974

Going ahead to step 8:
1409 divided by 974 is 1 with a remainder of 435.
The next digit of our result is 1. 
Result so far: 82521.0
If we subtract 974 from 1409, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 9:
4350 divided by 974 is 4 with a remainder of 454.
The number 4 becomes the next digit in our result. 
Result so far: 82521.4
The remainder is 454 after subtracting 3896 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 10:
When dividing 4540 by 974, we get 4 with a remainder of 644.
Put 4 as the next digit of the answer. 
Result so far: 82521.44
The remainder is 644 after subtracting 3896 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Our division results in 82521.44 with a remaining 0.644.
