78606958 divided by 486 
Our goal is to divide 78606958 by 486.

Let's proceed to step 1:
486 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 486

Moving on to step 2:
78 divided by 486 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 486

Moving on to step 3:
If we divide 786 by 486, we get 1 and a remainder of 300.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 300 after subtracting 486 from 786.
Bring next digit (0) of the dividend behind the 300 and repeat the process: 3000 / 486

Step 4:
The number 486 fits into 3000 6 times, leaving a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 2916 away from 3000, we end up with 84.
Bring next digit (6) of the dividend behind the 84 and repeat the process: 846 / 486

Advancing to step 5:
486 goes into 846 1 times with a remainder of 360.
Put 1 as the next digit of the answer. 
Result so far: 161.0
If we take 486 away from 846, we end up with 360.
Take the next digit (9) from the dividend and append it to 360, then repeat: 3609 / 486

On to step 6:
The number 486 fits into 3609 7 times, leaving a remainder of 207.
Record the quotient 7 as the next digit in the result. 
Result so far: 1617.0
Deduct 3402 from 3609 and we're left with 207.
Include the next digit (5) from the dividend after 207, then repeat: 2075 / 486

Step 7:
486 can be fit into 2075 4 times, resulting in a remainder of 131.
Use 4 as the next digit of our solution. 
Result so far: 16174.0
Subtract 1944 from 2075 to get 131.
Bring next digit (8) of the dividend behind the 131 and repeat the process: 1318 / 486

Going ahead to step 8:
486 goes into 1318 2 times with a remainder of 346.
Put 2 as the next digit of the answer. 
Result so far: 161742.0
Subtract 972 from 1318 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 9:
The number 486 fits into 3460 7 times, leaving a remainder of 58.
The next digit of our result is 7. 
Result so far: 161742.7
The remainder is 58 after subtracting 3402 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
580 divided by 486 is 1 with a remainder of 94.
The next digit of our result is 1. 
Result so far: 161742.71
If we subtract 486 from 580, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 11:
486 can be fit into 940 1 times, resulting in a remainder of 454.
The next digit of our result is 1. 
Result so far: 161742.711
Subtracting 486 from 940 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

The quotient of the division is 161742.711, and the remainder is 0.0454.
