87123112 divided by 478 
The aim is to understand the frequency of 478 in 87123112.

Going ahead to step 1:
8 divided by 478 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 478

Step 2:
When dividing 87 by 478, we get 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 478

Advancing to step 3:
871 divided by 478 is 1 with a remainder of 393.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 478 from 871 leaves us with 393.

Step 4:
478 can be fit into 3932 8 times, resulting in a remainder of 108.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 3824 from 3932 to get 108.
Append the next digit (3) from the dividend to 108 and continue with: 1083 / 478

Advancing to step 5:
If we divide 1083 by 478, we get 2 and a remainder of 127.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
Deduct 956 from 1083 and we're left with 127.
Include the next digit (1) from the dividend after 127, then repeat: 1271 / 478

Going ahead to step 6:
478 can be fit into 1271 2 times, resulting in a remainder of 315.
Use 2 as the next digit of our solution. 
Result so far: 1822.0
Subtracting 956 from 1271 leaves us with 315.
Append the next digit (1) from the dividend to 315 and continue with: 3151 / 478

Moving on to step 7:
478 can be fit into 3151 6 times, resulting in a remainder of 283.
Use 6 as the next digit of our solution. 
Result so far: 18226.0
Subtracting 2868 from 3151 leaves us with 283.
Take the next digit (2) from the dividend and append it to 283, then repeat: 2832 / 478

On to step 8:
2832 divided by 478 is 5 with a remainder of 442.
The number 5 becomes the next digit in our result. 
Result so far: 182265.0
If we take 2390 away from 2832, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 9:
478 goes into 4420 9 times with a remainder of 118.
Write down 9 as next digit of the result. 
Result so far: 182265.9
Deduct 4302 from 4420 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 10:
When dividing 1180 by 478, we get 2 with a remainder of 224.
The next digit of our result is 2. 
Result so far: 182265.92
The remainder is 224 after subtracting 956 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 11:
478 can be fit into 2240 4 times, resulting in a remainder of 328.
Use 4 as the next digit of our solution. 
Result so far: 182265.924
Deduct 1912 from 2240 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 12:
When dividing 3280 by 478, we get 6 with a remainder of 412.
Put 6 as the next digit of the answer. 
Result so far: 182265.9246
Deduct 2868 from 3280 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 13:
478 can be fit into 4120 8 times, resulting in a remainder of 296.
The number 8 becomes the next digit in our result. 
Result so far: 182265.92468
The remainder is 296 after subtracting 3824 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 14:
478 can be fit into 2960 6 times, resulting in a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 182265.924686
The remainder is 92 after subtracting 2868 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 15:
920 divided by 478 is 1 with a remainder of 442.
Put 1 as the next digit of the answer. 
Result so far: 182265.9246861
The remainder is 442 after subtracting 478 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Going ahead to step 16:
The number 478 fits into 4420 9 times, leaving a remainder of 118.
Record the quotient 9 as the next digit in the result. 
Result so far: 182265.92468619
Subtract 4302 from 4420 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The quotient of the division is 182265.92468619, and the remainder is 1.18e-07.
