Let's divide 78771851 by 473
The aim is to understand the frequency of 473 in 78771851.

On to step 1:
473 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 473

Step 2:
473 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 473

Moving on to step 3:
When dividing 787 by 473, we get 1 with a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 473 from 787 to get 314.
Bring next digit (7) of the dividend behind the 314 and repeat the process: 3147 / 473

Going ahead to step 4:
3147 divided by 473 is 6 with a remainder of 309.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 309 after subtracting 2838 from 3147.
Fetch the next digit (1) from the dividend, attach it to 309 and continue: 3091 / 473

On to step 5:
When dividing 3091 by 473, we get 6 with a remainder of 253.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
If we take 2838 away from 3091, we end up with 253.
Include the next digit (8) from the dividend after 253, then repeat: 2538 / 473

Going ahead to step 6:
If we divide 2538 by 473, we get 5 and a remainder of 173.
Put 5 as the next digit of the answer. 
Result so far: 1665.0
Deduct 2365 from 2538 and we're left with 173.
Append the next digit (5) from the dividend to 173 and continue with: 1735 / 473

Moving on to step 7:
473 can be fit into 1735 3 times, resulting in a remainder of 316.
Put 3 as the next digit of the answer. 
Result so far: 16653.0
Subtract 1419 from 1735 to get 316.
Grab the next digit (1) from the dividend, add it to 316, then carry on: 3161 / 473

Advancing to step 8:
If we divide 3161 by 473, we get 6 and a remainder of 323.
Put 6 as the next digit of the answer. 
Result so far: 166536.0
Subtract 2838 from 3161 to get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 9:
When dividing 3230 by 473, we get 6 with a remainder of 392.
Put 6 as the next digit of the answer. 
Result so far: 166536.6
Subtracting 2838 from 3230 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 10:
If we divide 3920 by 473, we get 8 and a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 166536.68
Subtract 3784 from 3920 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 11:
473 goes into 1360 2 times with a remainder of 414.
The number 2 becomes the next digit in our result. 
Result so far: 166536.682
Subtract 946 from 1360 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 12:
4140 divided by 473 is 8 with a remainder of 356.
Put 8 as the next digit of the answer. 
Result so far: 166536.6828
If we take 3784 away from 4140, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 13:
473 goes into 3560 7 times with a remainder of 249.
Record the quotient 7 as the next digit in the result. 
Result so far: 166536.68287
If we subtract 3311 from 3560, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Going ahead to step 14:
473 can be fit into 2490 5 times, resulting in a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 166536.682875
Subtract 2365 from 2490 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 15:
When dividing 1250 by 473, we get 2 with a remainder of 304.
Put 2 as the next digit of the answer. 
Result so far: 166536.6828752
Subtract 946 from 1250 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 16:
473 goes into 3040 6 times with a remainder of 202.
The number 6 becomes the next digit in our result. 
Result so far: 166536.68287526
Subtract 2838 from 3040 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The final outcome is 166536.68287526, with a leftover of 2.02e-07.
