77155855 divided by 407 
We want to figure out the number of times 77155855 can be divided by 407.

Let's proceed to step 1:
The number 407 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 407

Advancing to step 2:
If we divide 77 by 407, we get 0 and a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 407

Moving on to step 3:
If we divide 771 by 407, we get 1 and a remainder of 364.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 364 after subtracting 407 from 771.
Take the next digit (5) from the dividend and append it to 364, then repeat: 3645 / 407

Moving on to step 4:
If we divide 3645 by 407, we get 8 and a remainder of 389.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 3256 from 3645 leaves us with 389.
Bring next digit (5) of the dividend behind the 389 and repeat the process: 3895 / 407

Step 5:
3895 divided by 407 is 9 with a remainder of 232.
Write down 9 as next digit of the result. 
Result so far: 189.0
If we take 3663 away from 3895, we end up with 232.
Take the next digit (8) from the dividend and append it to 232, then repeat: 2328 / 407

Going ahead to step 6:
When dividing 2328 by 407, we get 5 with a remainder of 293.
The next digit of our result is 5. 
Result so far: 1895.0
Subtract 2035 from 2328 to get 293.
Take the next digit (5) from the dividend and append it to 293, then repeat: 2935 / 407

Going ahead to step 7:
The number 407 fits into 2935 7 times, leaving a remainder of 86.
Record the quotient 7 as the next digit in the result. 
Result so far: 18957.0
If we take 2849 away from 2935, we end up with 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 407

Let's proceed to step 8:
407 goes into 865 2 times with a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 189572.0
The remainder is 51 after subtracting 814 from 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
If we divide 510 by 407, we get 1 and a remainder of 103.
Put 1 as the next digit of the answer. 
Result so far: 189572.1
The remainder is 103 after subtracting 407 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 10:
The number 407 fits into 1030 2 times, leaving a remainder of 216.
The next digit of our result is 2. 
Result so far: 189572.12
If we take 814 away from 1030, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 11:
When dividing 2160 by 407, we get 5 with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 189572.125
The remainder is 125 after subtracting 2035 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 12:
407 can be fit into 1250 3 times, resulting in a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 189572.1253
Subtract 1221 from 1250 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
407 can be fit into 290 0 times, resulting in a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 189572.1253
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 14:
2900 divided by 407 is 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 189572.125307
If we subtract 2849 from 2900, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 15:
If we divide 510 by 407, we get 1 and a remainder of 103.
Use 1 as the next digit of our solution. 
Result so far: 189572.1253071
Deduct 407 from 510 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 16:
If we divide 1030 by 407, we get 2 and a remainder of 216.
Put 2 as the next digit of the answer. 
Result so far: 189572.12530712
Subtracting 814 from 1030 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

In conclusion, the division gives 189572.12530712 with a balance of 2.16e-07.
