We're dividing 43864735 by 978 
The aim is to understand the frequency of 978 in 43864735.

Moving on to step 1:
When dividing 4 by 978, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 978

Step 2:
43 divided by 978 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 978

On to step 3:
If we divide 438 by 978, we get 0 and a remainder of 438.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 438 to get 438.
Include the next digit (6) from the dividend after 438, then repeat: 4386 / 978

Going ahead to step 4:
978 can be fit into 4386 4 times, resulting in a remainder of 474.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3912 away from 4386, we end up with 474.
Fetch the next digit (4) from the dividend, attach it to 474 and continue: 4744 / 978

Advancing to step 5:
4744 divided by 978 is 4 with a remainder of 832.
Put 4 as the next digit of the answer. 
Result so far: 44.0
The remainder is 832 after subtracting 3912 from 4744.
Fetch the next digit (7) from the dividend, attach it to 832 and continue: 8327 / 978

Moving on to step 6:
978 can be fit into 8327 8 times, resulting in a remainder of 503.
The next digit of our result is 8. 
Result so far: 448.0
Deduct 7824 from 8327 and we're left with 503.
Append the next digit (3) from the dividend to 503 and continue with: 5033 / 978

Step 7:
If we divide 5033 by 978, we get 5 and a remainder of 143.
Write down 5 as next digit of the result. 
Result so far: 4485.0
If we take 4890 away from 5033, we end up with 143.
Bring next digit (5) of the dividend behind the 143 and repeat the process: 1435 / 978

Step 8:
1435 divided by 978 is 1 with a remainder of 457.
Write down 1 as next digit of the result. 
Result so far: 44851.0
Subtracting 978 from 1435 leaves us with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 9:
The number 978 fits into 4570 4 times, leaving a remainder of 658.
The number 4 becomes the next digit in our result. 
Result so far: 44851.4
If we take 3912 away from 4570, we end up with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

On to step 10:
978 can be fit into 6580 6 times, resulting in a remainder of 712.
Write down 6 as next digit of the result. 
Result so far: 44851.46
If we take 5868 away from 6580, we end up with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

On to step 11:
978 can be fit into 7120 7 times, resulting in a remainder of 274.
Put 7 as the next digit of the answer. 
Result so far: 44851.467
If we subtract 6846 from 7120, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 12:
If we divide 2740 by 978, we get 2 and a remainder of 784.
Record the quotient 2 as the next digit in the result. 
Result so far: 44851.4672
If we take 1956 away from 2740, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Let's proceed to step 13:
The number 978 fits into 7840 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 44851.46728
Subtract 7824 from 7840 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
978 can be fit into 160 0 times, resulting in a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 44851.46728
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
1600 divided by 978 is 1 with a remainder of 622.
The next digit of our result is 1. 
Result so far: 44851.4672801
If we subtract 978 from 1600, we get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Going ahead to step 16:
978 can be fit into 6220 6 times, resulting in a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 44851.46728016
Subtract 5868 from 6220 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final result is 44851.46728016 with a remainder of 3.52e-07.
