77021831 ÷ 208 
We want to figure out the number of times 77021831 can be divided by 208.

Going ahead to step 1:
7 divided by 208 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 208

Advancing to step 2:
208 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 208

Step 3:
When dividing 770 by 208, we get 3 with a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 624 from 770 leaves us with 146.
Include the next digit (2) from the dividend after 146, then repeat: 1462 / 208

Advancing to step 4:
When dividing 1462 by 208, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 37.0
Deduct 1456 from 1462 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 208

Let's proceed to step 5:
The number 208 fits into 61 0 times, leaving a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 370.0
Subtracting 0 from 61 leaves us with 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 208

Moving on to step 6:
The number 208 fits into 618 2 times, leaving a remainder of 202.
Put 2 as the next digit of the answer. 
Result so far: 3702.0
Subtracting 416 from 618 leaves us with 202.
Append the next digit (3) from the dividend to 202 and continue with: 2023 / 208

On to step 7:
2023 divided by 208 is 9 with a remainder of 151.
Write down 9 as next digit of the result. 
Result so far: 37029.0
If we subtract 1872 from 2023, we get 151.
Fetch the next digit (1) from the dividend, attach it to 151 and continue: 1511 / 208

On to step 8:
If we divide 1511 by 208, we get 7 and a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 370297.0
The remainder is 55 after subtracting 1456 from 1511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
If we divide 550 by 208, we get 2 and a remainder of 134.
The number 2 becomes the next digit in our result. 
Result so far: 370297.2
Subtracting 416 from 550 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
The number 208 fits into 1340 6 times, leaving a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 370297.26
Subtract 1248 from 1340 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 11:
920 divided by 208 is 4 with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 370297.264
The remainder is 88 after subtracting 832 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 12:
880 divided by 208 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 370297.2644
If we take 832 away from 880, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 370297.2644 with a balance of 0.00048.
