84486893 ÷ 900 
We want to divide 84486893 by 900.

Moving on to step 1:
If we divide 8 by 900, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 900

On to step 2:
The number 900 fits into 84 0 times, leaving a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Grab the next digit (4) from the dividend, add it to 84, then carry on: 844 / 900

Going ahead to step 3:
When dividing 844 by 900, we get 0 with a remainder of 844.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 844 to get 844.
Append the next digit (8) from the dividend to 844 and continue with: 8448 / 900

Step 4:
8448 divided by 900 is 9 with a remainder of 348.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 8100 away from 8448, we end up with 348.
Append the next digit (6) from the dividend to 348 and continue with: 3486 / 900

Step 5:
900 goes into 3486 3 times with a remainder of 786.
Write down 3 as next digit of the result. 
Result so far: 93.0
Subtracting 2700 from 3486 leaves us with 786.
Append the next digit (8) from the dividend to 786 and continue with: 7868 / 900

On to step 6:
7868 divided by 900 is 8 with a remainder of 668.
Use 8 as the next digit of our solution. 
Result so far: 938.0
The remainder is 668 after subtracting 7200 from 7868.
Include the next digit (9) from the dividend after 668, then repeat: 6689 / 900

Advancing to step 7:
900 can be fit into 6689 7 times, resulting in a remainder of 389.
Put 7 as the next digit of the answer. 
Result so far: 9387.0
If we take 6300 away from 6689, we end up with 389.
Take the next digit (3) from the dividend and append it to 389, then repeat: 3893 / 900

Going ahead to step 8:
The number 900 fits into 3893 4 times, leaving a remainder of 293.
Put 4 as the next digit of the answer. 
Result so far: 93874.0
Subtracting 3600 from 3893 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Advancing to step 9:
The number 900 fits into 2930 3 times, leaving a remainder of 230.
Use 3 as the next digit of our solution. 
Result so far: 93874.3
If we take 2700 away from 2930, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 10:
900 can be fit into 2300 2 times, resulting in a remainder of 500.
Use 2 as the next digit of our solution. 
Result so far: 93874.32
Deduct 1800 from 2300 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.

Step 11:
If we divide 5000 by 900, we get 5 and a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 93874.325
The remainder is 500 after subtracting 4500 from 5000.
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:
900 goes into 5000 5 times with a remainder of 500.
Put 5 as the next digit of the answer. 
Result so far: 93874.3255
If we take 4500 away from 5000, 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.

Our division results in 93874.3255 with a remaining 0.005.
