We divide 83978993 by 440
The aim is to understand the frequency of 440 in 83978993.

Moving on to step 1:
If we divide 8 by 440, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 440

Step 2:
When dividing 83 by 440, we get 0 with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 440

On to step 3:
The number 440 fits into 839 1 times, leaving a remainder of 399.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 399 after subtracting 440 from 839.
Bring next digit (7) of the dividend behind the 399 and repeat the process: 3997 / 440

Let's proceed to step 4:
If we divide 3997 by 440, we get 9 and a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 3960 away from 3997, we end up with 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 440

Let's proceed to step 5:
When dividing 378 by 440, we get 0 with a remainder of 378.
Put 0 as the next digit of the answer. 
Result so far: 190.0
The remainder is 378 after subtracting 0 from 378.
Fetch the next digit (9) from the dividend, attach it to 378 and continue: 3789 / 440

On to step 6:
If we divide 3789 by 440, we get 8 and a remainder of 269.
Record the quotient 8 as the next digit in the result. 
Result so far: 1908.0
Subtracting 3520 from 3789 leaves us with 269.
Take the next digit (9) from the dividend and append it to 269, then repeat: 2699 / 440

On to step 7:
440 goes into 2699 6 times with a remainder of 59.
The next digit of our result is 6. 
Result so far: 19086.0
Subtracting 2640 from 2699 leaves us with 59.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 440

Advancing to step 8:
593 divided by 440 is 1 with a remainder of 153.
The next digit of our result is 1. 
Result so far: 190861.0
If we take 440 away from 593, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 9:
The number 440 fits into 1530 3 times, leaving a remainder of 210.
The next digit of our result is 3. 
Result so far: 190861.3
The remainder is 210 after subtracting 1320 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
440 can be fit into 2100 4 times, resulting in a remainder of 340.
The next digit of our result is 4. 
Result so far: 190861.34
If we take 1760 away from 2100, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 11:
440 goes into 3400 7 times with a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 190861.347
Subtract 3080 from 3400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 12:
If we divide 3200 by 440, we get 7 and a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 190861.3477
If we take 3080 away from 3200, we end up 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.

The final result is 190861.3477 with a remainder of 0.0012.
