77478187 divided by 427 
We want to divide 77478187 by 427.

Step 1:
427 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 427

Moving on to step 2:
If we divide 77 by 427, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 427

Let's proceed to step 3:
When dividing 774 by 427, we get 1 with a remainder of 347.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 347 after subtracting 427 from 774.
Append the next digit (7) from the dividend to 347 and continue with: 3477 / 427

Going ahead to step 4:
427 can be fit into 3477 8 times, resulting in a remainder of 61.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 3416 from 3477 leaves us with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 427

Step 5:
The number 427 fits into 618 1 times, leaving a remainder of 191.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
The remainder is 191 after subtracting 427 from 618.
Append the next digit (1) from the dividend to 191 and continue with: 1911 / 427

Let's proceed to step 6:
427 goes into 1911 4 times with a remainder of 203.
Record the quotient 4 as the next digit in the result. 
Result so far: 1814.0
The remainder is 203 after subtracting 1708 from 1911.
Bring next digit (8) of the dividend behind the 203 and repeat the process: 2038 / 427

Going ahead to step 7:
When dividing 2038 by 427, we get 4 with a remainder of 330.
Put 4 as the next digit of the answer. 
Result so far: 18144.0
If we take 1708 away from 2038, we end up with 330.
Include the next digit (7) from the dividend after 330, then repeat: 3307 / 427

Step 8:
427 goes into 3307 7 times with a remainder of 318.
The next digit of our result is 7. 
Result so far: 181447.0
The remainder is 318 after subtracting 2989 from 3307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 9:
When dividing 3180 by 427, we get 7 with a remainder of 191.
Use 7 as the next digit of our solution. 
Result so far: 181447.7
Subtracting 2989 from 3180 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 10:
If we divide 1910 by 427, we get 4 and a remainder of 202.
Write down 4 as next digit of the result. 
Result so far: 181447.74
Subtracting 1708 from 1910 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 11:
When dividing 2020 by 427, we get 4 with a remainder of 312.
Write down 4 as next digit of the result. 
Result so far: 181447.744
If we take 1708 away from 2020, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final outcome is 181447.744, with a leftover of 0.0312.
