77048220 ÷ 476 
The aim is to understand the frequency of 476 in 77048220.

On to step 1:
476 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 476

Moving on to step 2:
If we divide 77 by 476, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 476

Let's proceed to step 3:
If we divide 770 by 476, we get 1 and a remainder of 294.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 476 from 770, we get 294.
Bring next digit (4) of the dividend behind the 294 and repeat the process: 2944 / 476

On to step 4:
If we divide 2944 by 476, we get 6 and a remainder of 88.
The next digit of our result is 6. 
Result so far: 16.0
If we take 2856 away from 2944, we end up with 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 476

Advancing to step 5:
The number 476 fits into 888 1 times, leaving a remainder of 412.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
If we subtract 476 from 888, we get 412.
Append the next digit (2) from the dividend to 412 and continue with: 4122 / 476

Let's proceed to step 6:
4122 divided by 476 is 8 with a remainder of 314.
Record the quotient 8 as the next digit in the result. 
Result so far: 1618.0
Subtract 3808 from 4122 to get 314.
Grab the next digit (2) from the dividend, add it to 314, then carry on: 3142 / 476

Let's proceed to step 7:
3142 divided by 476 is 6 with a remainder of 286.
Use 6 as the next digit of our solution. 
Result so far: 16186.0
Deduct 2856 from 3142 and we're left with 286.
Include the next digit (0) from the dividend after 286, then repeat: 2860 / 476

Moving on to step 8:
476 can be fit into 2860 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 161866.0
Deduct 2856 from 2860 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.

Advancing to step 9:
When dividing 40 by 476, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 161866.0
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.

Let's proceed to step 10:
The number 476 fits into 400 0 times, leaving a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 161866.0
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.

The final result is 161866.0 with a remainder of 0.4.
