77778906 divided by 316 
We want to figure out the number of times 77778906 can be divided by 316.

Let's proceed to step 1:
When dividing 7 by 316, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
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 / 316

Let's proceed to step 2:
If we divide 77 by 316, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 316

Moving on to step 3:
316 can be fit into 777 2 times, resulting in a remainder of 145.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 145 after subtracting 632 from 777.
Append the next digit (7) from the dividend to 145 and continue with: 1457 / 316

Let's proceed to step 4:
1457 divided by 316 is 4 with a remainder of 193.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 1264 from 1457 to get 193.
Append the next digit (8) from the dividend to 193 and continue with: 1938 / 316

Going ahead to step 5:
316 goes into 1938 6 times with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 246.0
Subtract 1896 from 1938 to get 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 316

Advancing to step 6:
316 can be fit into 429 1 times, resulting in a remainder of 113.
The next digit of our result is 1. 
Result so far: 2461.0
The remainder is 113 after subtracting 316 from 429.
Fetch the next digit (0) from the dividend, attach it to 113 and continue: 1130 / 316

Let's proceed to step 7:
The number 316 fits into 1130 3 times, leaving a remainder of 182.
Record the quotient 3 as the next digit in the result. 
Result so far: 24613.0
If we take 948 away from 1130, we end up with 182.
Grab the next digit (6) from the dividend, add it to 182, then carry on: 1826 / 316

Let's proceed to step 8:
If we divide 1826 by 316, we get 5 and a remainder of 246.
The next digit of our result is 5. 
Result so far: 246135.0
If we subtract 1580 from 1826, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 9:
When dividing 2460 by 316, we get 7 with a remainder of 248.
The next digit of our result is 7. 
Result so far: 246135.7
Deduct 2212 from 2460 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 10:
If we divide 2480 by 316, we get 7 and a remainder of 268.
Put 7 as the next digit of the answer. 
Result so far: 246135.77
Deduct 2212 from 2480 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final outcome is 246135.77, with a leftover of 0.268.
