We look at the division of 77861082 by 453 
Let's see how many times 453 fits into 77861082.

On to step 1:
The number 453 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 453

On to step 2:
When dividing 77 by 453, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 453

Advancing to step 3:
The number 453 fits into 778 1 times, leaving a remainder of 325.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 325 after subtracting 453 from 778.
Fetch the next digit (6) from the dividend, attach it to 325 and continue: 3256 / 453

On to step 4:
3256 divided by 453 is 7 with a remainder of 85.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 3171 from 3256 to get 85.
Fetch the next digit (1) from the dividend, attach it to 85 and continue: 851 / 453

Advancing to step 5:
851 divided by 453 is 1 with a remainder of 398.
Put 1 as the next digit of the answer. 
Result so far: 171.0
If we take 453 away from 851, we end up with 398.
Fetch the next digit (0) from the dividend, attach it to 398 and continue: 3980 / 453

Advancing to step 6:
453 goes into 3980 8 times with a remainder of 356.
The number 8 becomes the next digit in our result. 
Result so far: 1718.0
If we subtract 3624 from 3980, we get 356.
Fetch the next digit (8) from the dividend, attach it to 356 and continue: 3568 / 453

Moving on to step 7:
The number 453 fits into 3568 7 times, leaving a remainder of 397.
The next digit of our result is 7. 
Result so far: 17187.0
Subtract 3171 from 3568 to get 397.
Append the next digit (2) from the dividend to 397 and continue with: 3972 / 453

Advancing to step 8:
The number 453 fits into 3972 8 times, leaving a remainder of 348.
Put 8 as the next digit of the answer. 
Result so far: 171878.0
Deduct 3624 from 3972 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 9:
3480 divided by 453 is 7 with a remainder of 309.
Use 7 as the next digit of our solution. 
Result so far: 171878.7
Deduct 3171 from 3480 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 10:
When dividing 3090 by 453, we get 6 with a remainder of 372.
Use 6 as the next digit of our solution. 
Result so far: 171878.76
If we take 2718 away from 3090, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 11:
If we divide 3720 by 453, we get 8 and a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 171878.768
Subtract 3624 from 3720 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 12:
If we divide 960 by 453, we get 2 and a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 171878.7682
Deduct 906 from 960 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
540 divided by 453 is 1 with a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 171878.76821
If we take 453 away from 540, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 14:
453 goes into 870 1 times with a remainder of 417.
Use 1 as the next digit of our solution. 
Result so far: 171878.768211
Deduct 453 from 870 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

After the division, we end up with 171878.768211 and a remainder of 4.17e-05.
