84457830 ÷ 550 
We want to figure out the number of times 84457830 can be divided by 550.

Advancing to step 1:
550 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 550

Step 2:
550 goes into 84 0 times with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 550

Let's proceed to step 3:
550 can be fit into 844 1 times, resulting in a remainder of 294.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 550 from 844 to get 294.
Grab the next digit (5) from the dividend, add it to 294, then carry on: 2945 / 550

Advancing to step 4:
2945 divided by 550 is 5 with a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2750 from 2945 and we're left with 195.
Take the next digit (7) from the dividend and append it to 195, then repeat: 1957 / 550

Let's proceed to step 5:
When dividing 1957 by 550, we get 3 with a remainder of 307.
The next digit of our result is 3. 
Result so far: 153.0
If we take 1650 away from 1957, we end up with 307.
Append the next digit (8) from the dividend to 307 and continue with: 3078 / 550

Let's proceed to step 6:
When dividing 3078 by 550, we get 5 with a remainder of 328.
The number 5 becomes the next digit in our result. 
Result so far: 1535.0
If we take 2750 away from 3078, we end up with 328.
Include the next digit (3) from the dividend after 328, then repeat: 3283 / 550

Moving on to step 7:
If we divide 3283 by 550, we get 5 and a remainder of 533.
Record the quotient 5 as the next digit in the result. 
Result so far: 15355.0
Subtracting 2750 from 3283 leaves us with 533.
Append the next digit (0) from the dividend to 533 and continue with: 5330 / 550

Advancing to step 8:
550 goes into 5330 9 times with a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 153559.0
If we subtract 4950 from 5330, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 9:
550 can be fit into 3800 6 times, resulting in a remainder of 500.
The next digit of our result is 6. 
Result so far: 153559.6
Subtract 3300 from 3800 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
If we divide 5000 by 550, we get 9 and a remainder of 50.
The next digit of our result is 9. 
Result so far: 153559.69
Deduct 4950 from 5000 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
If we divide 500 by 550, we get 0 and a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 153559.69
If we take 0 away from 500, we end up 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.

On to step 12:
550 can be fit into 5000 9 times, resulting in a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 153559.6909
The remainder is 50 after subtracting 4950 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
When dividing 500 by 550, we get 0 with a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 153559.6909
Subtracting 0 from 500 leaves us 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.

Advancing to step 14:
5000 divided by 550 is 9 with a remainder of 50.
The next digit of our result is 9. 
Result so far: 153559.690909
If we take 4950 away from 5000, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 15:
The number 550 fits into 500 0 times, leaving a remainder of 500.
The next digit of our result is 0. 
Result so far: 153559.690909
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 16:
5000 divided by 550 is 9 with a remainder of 50.
The next digit of our result is 9. 
Result so far: 153559.69090909
If we subtract 4950 from 5000, 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.

After the division, we end up with 153559.69090909 and a remainder of 5e-08.
