We divide 13088398 by 978
The aim is to understand the frequency of 978 in 13088398.

Moving on to step 1:
978 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 978

Going ahead to step 2:
978 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 978

Advancing to step 3:
If we divide 130 by 978, we get 0 and a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 130 after subtracting 0 from 130.
Bring next digit (8) of the dividend behind the 130 and repeat the process: 1308 / 978

Let's proceed to step 4:
978 can be fit into 1308 1 times, resulting in a remainder of 330.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 330 after subtracting 978 from 1308.
Include the next digit (8) from the dividend after 330, then repeat: 3308 / 978

Going ahead to step 5:
If we divide 3308 by 978, we get 3 and a remainder of 374.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 2934 from 3308 leaves us with 374.
Append the next digit (3) from the dividend to 374 and continue with: 3743 / 978

On to step 6:
The number 978 fits into 3743 3 times, leaving a remainder of 809.
The next digit of our result is 3. 
Result so far: 133.0
Subtracting 2934 from 3743 leaves us with 809.
Append the next digit (9) from the dividend to 809 and continue with: 8099 / 978

Going ahead to step 7:
978 goes into 8099 8 times with a remainder of 275.
Use 8 as the next digit of our solution. 
Result so far: 1338.0
If we subtract 7824 from 8099, we get 275.
Grab the next digit (8) from the dividend, add it to 275, then carry on: 2758 / 978

Step 8:
2758 divided by 978 is 2 with a remainder of 802.
Put 2 as the next digit of the answer. 
Result so far: 13382.0
If we subtract 1956 from 2758, we get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

On to step 9:
If we divide 8020 by 978, we get 8 and a remainder of 196.
The next digit of our result is 8. 
Result so far: 13382.8
If we subtract 7824 from 8020, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 10:
1960 divided by 978 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 13382.82
Deduct 1956 from 1960 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
978 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 13382.82
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
400 divided by 978 is 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 13382.82
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 13382.82 with a remaining 0.004.
