41066800 ÷ 978 
The aim is to understand the frequency of 978 in 41066800.

On to step 1:
The number 978 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 978

On to step 2:
978 can be fit into 41 0 times, resulting in a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Bring next digit (0) of the dividend behind the 41 and repeat the process: 410 / 978

Moving on to step 3:
978 goes into 410 0 times with a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 410 to get 410.
Grab the next digit (6) from the dividend, add it to 410, then carry on: 4106 / 978

Advancing to step 4:
978 can be fit into 4106 4 times, resulting in a remainder of 194.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3912 from 4106 and we're left with 194.
Bring next digit (6) of the dividend behind the 194 and repeat the process: 1946 / 978

Step 5:
978 can be fit into 1946 1 times, resulting in a remainder of 968.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 978 from 1946 leaves us with 968.
Grab the next digit (8) from the dividend, add it to 968, then carry on: 9688 / 978

Going ahead to step 6:
If we divide 9688 by 978, we get 9 and a remainder of 886.
Write down 9 as next digit of the result. 
Result so far: 419.0
If we subtract 8802 from 9688, we get 886.
Grab the next digit (0) from the dividend, add it to 886, then carry on: 8860 / 978

On to step 7:
8860 divided by 978 is 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 4199.0
If we subtract 8802 from 8860, we get 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 978

Let's proceed to step 8:
978 goes into 580 0 times with a remainder of 580.
Use 0 as the next digit of our solution. 
Result so far: 41990.0
Deduct 0 from 580 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 9:
When dividing 5800 by 978, we get 5 with a remainder of 910.
Record the quotient 5 as the next digit in the result. 
Result so far: 41990.5
Subtracting 4890 from 5800 leaves us with 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

Moving on to step 10:
If we divide 9100 by 978, we get 9 and a remainder of 298.
Use 9 as the next digit of our solution. 
Result so far: 41990.59
Deduct 8802 from 9100 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 11:
When dividing 2980 by 978, we get 3 with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 41990.593
If we take 2934 away from 2980, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
When dividing 460 by 978, we get 0 with a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 41990.593
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 13:
4600 divided by 978 is 4 with a remainder of 688.
Record the quotient 4 as the next digit in the result. 
Result so far: 41990.59304
Deduct 3912 from 4600 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 14:
When dividing 6880 by 978, we get 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 41990.593047
Deduct 6846 from 6880 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 15:
When dividing 340 by 978, we get 0 with a remainder of 340.
The next digit of our result is 0. 
Result so far: 41990.593047
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 16:
When dividing 3400 by 978, we get 3 with a remainder of 466.
Record the quotient 3 as the next digit in the result. 
Result so far: 41990.59304703
Subtracting 2934 from 3400 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

After the division, we end up with 41990.59304703 and a remainder of 4.66e-07.
