Let's divide 78766120 by 406
We're looking to find how many times 406 goes into 78766120.

Step 1:
If we divide 7 by 406, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 406

Going ahead to step 2:
The number 406 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 406

Going ahead to step 3:
787 divided by 406 is 1 with a remainder of 381.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 406 from 787 to get 381.
Fetch the next digit (6) from the dividend, attach it to 381 and continue: 3816 / 406

Advancing to step 4:
406 can be fit into 3816 9 times, resulting in a remainder of 162.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 3654 away from 3816, we end up with 162.
Append the next digit (6) from the dividend to 162 and continue with: 1626 / 406

Moving on to step 5:
1626 divided by 406 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 194.0
Deduct 1624 from 1626 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 406

Moving on to step 6:
21 divided by 406 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 1940.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 406

Step 7:
406 can be fit into 212 0 times, resulting in a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 19400.0
Subtracting 0 from 212 leaves us with 212.
Bring next digit (0) of the dividend behind the 212 and repeat the process: 2120 / 406

Let's proceed to step 8:
406 can be fit into 2120 5 times, resulting in a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 194005.0
Subtracting 2030 from 2120 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 9:
The number 406 fits into 900 2 times, leaving a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 194005.2
Deduct 812 from 900 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
880 divided by 406 is 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 194005.22
If we subtract 812 from 880, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 194005.22, and the remainder is 0.068.
