We look at the division of 77380512 by 426 
Let's see how many times 426 fits into 77380512.

On to step 1:
When dividing 7 by 426, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 426

Going ahead to step 2:
If we divide 77 by 426, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 426

On to step 3:
773 divided by 426 is 1 with a remainder of 347.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 426 from 773, we get 347.
Take the next digit (8) from the dividend and append it to 347, then repeat: 3478 / 426

Advancing to step 4:
The number 426 fits into 3478 8 times, leaving a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 3408 from 3478 leaves us with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 426

On to step 5:
426 can be fit into 700 1 times, resulting in a remainder of 274.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
If we take 426 away from 700, we end up with 274.
Grab the next digit (5) from the dividend, add it to 274, then carry on: 2745 / 426

Going ahead to step 6:
When dividing 2745 by 426, we get 6 with a remainder of 189.
Write down 6 as next digit of the result. 
Result so far: 1816.0
Subtract 2556 from 2745 to get 189.
Fetch the next digit (1) from the dividend, attach it to 189 and continue: 1891 / 426

Let's proceed to step 7:
If we divide 1891 by 426, we get 4 and a remainder of 187.
Put 4 as the next digit of the answer. 
Result so far: 18164.0
The remainder is 187 after subtracting 1704 from 1891.
Append the next digit (2) from the dividend to 187 and continue with: 1872 / 426

Advancing to step 8:
1872 divided by 426 is 4 with a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 181644.0
The remainder is 168 after subtracting 1704 from 1872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 9:
When dividing 1680 by 426, we get 3 with a remainder of 402.
Use 3 as the next digit of our solution. 
Result so far: 181644.3
If we subtract 1278 from 1680, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 10:
4020 divided by 426 is 9 with a remainder of 186.
Put 9 as the next digit of the answer. 
Result so far: 181644.39
Subtracting 3834 from 4020 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 11:
426 can be fit into 1860 4 times, resulting in a remainder of 156.
Use 4 as the next digit of our solution. 
Result so far: 181644.394
If we take 1704 away from 1860, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 12:
426 can be fit into 1560 3 times, resulting in a remainder of 282.
The number 3 becomes the next digit in our result. 
Result so far: 181644.3943
If we take 1278 away from 1560, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 13:
2820 divided by 426 is 6 with a remainder of 264.
The next digit of our result is 6. 
Result so far: 181644.39436
If we subtract 2556 from 2820, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 14:
The number 426 fits into 2640 6 times, leaving a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 181644.394366
If we take 2556 away from 2640, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 181644.394366 with a remainder of 8.4e-06.
