We're dividing 15629041 by 978 
The aim is to understand the frequency of 978 in 15629041.

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.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 978

Step 2:
When dividing 15 by 978, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 978

Moving on to step 3:
156 divided by 978 is 0 with a remainder of 156.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 156, we get 156.
Append the next digit (2) from the dividend to 156 and continue with: 1562 / 978

Step 4:
If we divide 1562 by 978, we get 1 and a remainder of 584.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 978 from 1562 leaves us with 584.
Grab the next digit (9) from the dividend, add it to 584, then carry on: 5849 / 978

Advancing to step 5:
The number 978 fits into 5849 5 times, leaving a remainder of 959.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 4890 away from 5849, we end up with 959.
Append the next digit (0) from the dividend to 959 and continue with: 9590 / 978

On to step 6:
If we divide 9590 by 978, we get 9 and a remainder of 788.
The next digit of our result is 9. 
Result so far: 159.0
The remainder is 788 after subtracting 8802 from 9590.
Take the next digit (4) from the dividend and append it to 788, then repeat: 7884 / 978

On to step 7:
If we divide 7884 by 978, we get 8 and a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 1598.0
The remainder is 60 after subtracting 7824 from 7884.
Take the next digit (1) from the dividend and append it to 60, then repeat: 601 / 978

Going ahead to step 8:
601 divided by 978 is 0 with a remainder of 601.
Write down 0 as next digit of the result. 
Result so far: 15980.0
Subtract 0 from 601 to get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Moving on to step 9:
If we divide 6010 by 978, we get 6 and a remainder of 142.
The number 6 becomes the next digit in our result. 
Result so far: 15980.6
If we take 5868 away from 6010, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 10:
The number 978 fits into 1420 1 times, leaving a remainder of 442.
The next digit of our result is 1. 
Result so far: 15980.61
If we subtract 978 from 1420, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 11:
When dividing 4420 by 978, we get 4 with a remainder of 508.
Put 4 as the next digit of the answer. 
Result so far: 15980.614
If we take 3912 away from 4420, we end up with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 12:
978 can be fit into 5080 5 times, resulting in a remainder of 190.
The next digit of our result is 5. 
Result so far: 15980.6145
If we subtract 4890 from 5080, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 13:
978 can be fit into 1900 1 times, resulting in a remainder of 922.
The next digit of our result is 1. 
Result so far: 15980.61451
The remainder is 922 after subtracting 978 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9220, and continue the process.

On to step 14:
The number 978 fits into 9220 9 times, leaving a remainder of 418.
Write down 9 as next digit of the result. 
Result so far: 15980.614519
Subtracting 8802 from 9220 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 15:
The number 978 fits into 4180 4 times, leaving a remainder of 268.
The next digit of our result is 4. 
Result so far: 15980.6145194
If we take 3912 away from 4180, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 16:
2680 divided by 978 is 2 with a remainder of 724.
Write down 2 as next digit of the result. 
Result so far: 15980.61451942
If we take 1956 away from 2680, we end up with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Our division results in 15980.61451942 with a remaining 7.24e-07.
