We're dividing 70343456 by 978 
The aim is to understand the frequency of 978 in 70343456.

Moving on to step 1:
When dividing 7 by 978, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 978

Advancing to step 2:
978 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 978

On to step 3:
When dividing 703 by 978, we get 0 with a remainder of 703.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 703 and we're left with 703.
Take the next digit (4) from the dividend and append it to 703, then repeat: 7034 / 978

Moving on to step 4:
978 goes into 7034 7 times with a remainder of 188.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 6846 from 7034 to get 188.
Bring next digit (3) of the dividend behind the 188 and repeat the process: 1883 / 978

Let's proceed to step 5:
When dividing 1883 by 978, we get 1 with a remainder of 905.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we subtract 978 from 1883, we get 905.
Fetch the next digit (4) from the dividend, attach it to 905 and continue: 9054 / 978

Advancing to step 6:
If we divide 9054 by 978, we get 9 and a remainder of 252.
Use 9 as the next digit of our solution. 
Result so far: 719.0
If we take 8802 away from 9054, we end up with 252.
Include the next digit (5) from the dividend after 252, then repeat: 2525 / 978

Step 7:
If we divide 2525 by 978, we get 2 and a remainder of 569.
Write down 2 as next digit of the result. 
Result so far: 7192.0
Deduct 1956 from 2525 and we're left with 569.
Fetch the next digit (6) from the dividend, attach it to 569 and continue: 5696 / 978

Going ahead to step 8:
978 goes into 5696 5 times with a remainder of 806.
Put 5 as the next digit of the answer. 
Result so far: 71925.0
The remainder is 806 after subtracting 4890 from 5696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Moving on to step 9:
When dividing 8060 by 978, we get 8 with a remainder of 236.
The number 8 becomes the next digit in our result. 
Result so far: 71925.8
Deduct 7824 from 8060 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 10:
2360 divided by 978 is 2 with a remainder of 404.
The number 2 becomes the next digit in our result. 
Result so far: 71925.82
The remainder is 404 after subtracting 1956 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 11:
If we divide 4040 by 978, we get 4 and a remainder of 128.
The next digit of our result is 4. 
Result so far: 71925.824
The remainder is 128 after subtracting 3912 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 12:
1280 divided by 978 is 1 with a remainder of 302.
Put 1 as the next digit of the answer. 
Result so far: 71925.8241
The remainder is 302 after subtracting 978 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 13:
If we divide 3020 by 978, we get 3 and a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 71925.82413
Deduct 2934 from 3020 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 14:
860 divided by 978 is 0 with a remainder of 860.
The number 0 becomes the next digit in our result. 
Result so far: 71925.82413
The remainder is 860 after subtracting 0 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Advancing to step 15:
If we divide 8600 by 978, we get 8 and a remainder of 776.
Use 8 as the next digit of our solution. 
Result so far: 71925.8241308
If we take 7824 away from 8600, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Advancing to step 16:
When dividing 7760 by 978, we get 7 with a remainder of 914.
Record the quotient 7 as the next digit in the result. 
Result so far: 71925.82413087
Subtract 6846 from 7760 to get 914.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9140, and continue the process.

The final result is 71925.82413087 with a remainder of 9.14e-07.
