We're dividing 4231988 by 779 
We want to figure out the number of times 4231988 can be divided by 779.

On to step 1:
When dividing 4 by 779, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 779

Going ahead to step 2:
When dividing 42 by 779, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 779

Moving on to step 3:
When dividing 423 by 779, we get 0 with a remainder of 423.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 423 and we're left with 423.
Include the next digit (1) from the dividend after 423, then repeat: 4231 / 779

Step 4:
779 goes into 4231 5 times with a remainder of 336.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 3895 from 4231, we get 336.
Append the next digit (9) from the dividend to 336 and continue with: 3369 / 779

Going ahead to step 5:
When dividing 3369 by 779, we get 4 with a remainder of 253.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Subtracting 3116 from 3369 leaves us with 253.
Append the next digit (8) from the dividend to 253 and continue with: 2538 / 779

Let's proceed to step 6:
779 goes into 2538 3 times with a remainder of 201.
Record the quotient 3 as the next digit in the result. 
Result so far: 543.0
If we take 2337 away from 2538, we end up with 201.
Bring next digit (8) of the dividend behind the 201 and repeat the process: 2018 / 779

Advancing to step 7:
If we divide 2018 by 779, we get 2 and a remainder of 460.
The next digit of our result is 2. 
Result so far: 5432.0
The remainder is 460 after subtracting 1558 from 2018.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 8:
The number 779 fits into 4600 5 times, leaving a remainder of 705.
Use 5 as the next digit of our solution. 
Result so far: 5432.5
Subtract 3895 from 4600 to get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Advancing to step 9:
779 goes into 7050 9 times with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 5432.59
Deduct 7011 from 7050 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
779 goes into 390 0 times with a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 5432.59
The remainder is 390 after subtracting 0 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 11:
3900 divided by 779 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5432.5905
If we take 3895 away from 3900, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
When dividing 50 by 779, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 5432.5905
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
500 divided by 779 is 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 5432.5905
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 5432.5905 and a remainder of 5e-05.
