77907419 ÷ 428 
Our goal is to divide 77907419 by 428.

Let's proceed to step 1:
The number 428 fits into 7 0 times, leaving 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 / 428

On to step 2:
The number 428 fits into 77 0 times, leaving a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 428

Let's proceed to step 3:
428 can be fit into 779 1 times, resulting in a remainder of 351.
The next digit of our result is 1. 
Result so far: 1.0
If we take 428 away from 779, we end up with 351.
Take the next digit (0) from the dividend and append it to 351, then repeat: 3510 / 428

On to step 4:
When dividing 3510 by 428, we get 8 with a remainder of 86.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 3424 from 3510, we get 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 428

Step 5:
When dividing 867 by 428, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
The remainder is 11 after subtracting 856 from 867.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 428

Advancing to step 6:
The number 428 fits into 114 0 times, leaving a remainder of 114.
Write down 0 as next digit of the result. 
Result so far: 1820.0
If we take 0 away from 114, we end up with 114.
Include the next digit (1) from the dividend after 114, then repeat: 1141 / 428

Going ahead to step 7:
428 goes into 1141 2 times with a remainder of 285.
The next digit of our result is 2. 
Result so far: 18202.0
Deduct 856 from 1141 and we're left with 285.
Bring next digit (9) of the dividend behind the 285 and repeat the process: 2859 / 428

Let's proceed to step 8:
When dividing 2859 by 428, we get 6 with a remainder of 291.
Record the quotient 6 as the next digit in the result. 
Result so far: 182026.0
Subtracting 2568 from 2859 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Going ahead to step 9:
2910 divided by 428 is 6 with a remainder of 342.
Put 6 as the next digit of the answer. 
Result so far: 182026.6
Deduct 2568 from 2910 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 10:
If we divide 3420 by 428, we get 7 and a remainder of 424.
The next digit of our result is 7. 
Result so far: 182026.67
Subtracting 2996 from 3420 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 11:
428 goes into 4240 9 times with a remainder of 388.
The next digit of our result is 9. 
Result so far: 182026.679
Deduct 3852 from 4240 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 12:
428 goes into 3880 9 times with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 182026.6799
The remainder is 28 after subtracting 3852 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 182026.6799 with a balance of 0.00028.
