We're dividing 40548613 by 978 
The aim is to understand the frequency of 978 in 40548613.

On to step 1:
When dividing 4 by 978, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 978

On to step 2:
When dividing 40 by 978, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 978

Step 3:
If we divide 405 by 978, we get 0 and a remainder of 405.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 405 and we're left with 405.
Take the next digit (4) from the dividend and append it to 405, then repeat: 4054 / 978

Moving on to step 4:
If we divide 4054 by 978, we get 4 and a remainder of 142.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 3912 from 4054 leaves us with 142.
Grab the next digit (8) from the dividend, add it to 142, then carry on: 1428 / 978

Step 5:
1428 divided by 978 is 1 with a remainder of 450.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtract 978 from 1428 to get 450.
Include the next digit (6) from the dividend after 450, then repeat: 4506 / 978

Moving on to step 6:
The number 978 fits into 4506 4 times, leaving a remainder of 594.
The number 4 becomes the next digit in our result. 
Result so far: 414.0
If we take 3912 away from 4506, we end up with 594.
Fetch the next digit (1) from the dividend, attach it to 594 and continue: 5941 / 978

Moving on to step 7:
5941 divided by 978 is 6 with a remainder of 73.
The next digit of our result is 6. 
Result so far: 4146.0
Subtracting 5868 from 5941 leaves us with 73.
Grab the next digit (3) from the dividend, add it to 73, then carry on: 733 / 978

Moving on to step 8:
733 divided by 978 is 0 with a remainder of 733.
Use 0 as the next digit of our solution. 
Result so far: 41460.0
Subtract 0 from 733 to get 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Advancing to step 9:
The number 978 fits into 7330 7 times, leaving a remainder of 484.
Put 7 as the next digit of the answer. 
Result so far: 41460.7
Subtracting 6846 from 7330 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 10:
If we divide 4840 by 978, we get 4 and a remainder of 928.
Put 4 as the next digit of the answer. 
Result so far: 41460.74
The remainder is 928 after subtracting 3912 from 4840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

Let's proceed to step 11:
9280 divided by 978 is 9 with a remainder of 478.
Record the quotient 9 as the next digit in the result. 
Result so far: 41460.749
Subtract 8802 from 9280 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 12:
The number 978 fits into 4780 4 times, leaving a remainder of 868.
Record the quotient 4 as the next digit in the result. 
Result so far: 41460.7494
Deduct 3912 from 4780 and we're left with 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Going ahead to step 13:
If we divide 8680 by 978, we get 8 and a remainder of 856.
The next digit of our result is 8. 
Result so far: 41460.74948
Subtracting 7824 from 8680 leaves us with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Moving on to step 14:
When dividing 8560 by 978, we get 8 with a remainder of 736.
Put 8 as the next digit of the answer. 
Result so far: 41460.749488
If we subtract 7824 from 8560, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The final outcome is 41460.749488, with a leftover of 7.36e-05.
