84989243 ÷ 816 
We want to divide 84989243 by 816.

On to step 1:
8 divided by 816 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 816

Let's proceed to step 2:
816 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
Subtracting 0 from 84 leaves us with 84.
Take the next digit (9) from the dividend and append it to 84, then repeat: 849 / 816

Let's proceed to step 3:
When dividing 849 by 816, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 816 from 849 leaves us with 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 816

Advancing to step 4:
If we divide 338 by 816, we get 0 and a remainder of 338.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 338 and we're left with 338.
Take the next digit (9) from the dividend and append it to 338, then repeat: 3389 / 816

Step 5:
When dividing 3389 by 816, we get 4 with a remainder of 125.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Deduct 3264 from 3389 and we're left with 125.
Fetch the next digit (2) from the dividend, attach it to 125 and continue: 1252 / 816

Moving on to step 6:
The number 816 fits into 1252 1 times, leaving a remainder of 436.
The next digit of our result is 1. 
Result so far: 1041.0
Subtracting 816 from 1252 leaves us with 436.
Bring next digit (4) of the dividend behind the 436 and repeat the process: 4364 / 816

Advancing to step 7:
If we divide 4364 by 816, we get 5 and a remainder of 284.
Write down 5 as next digit of the result. 
Result so far: 10415.0
Subtracting 4080 from 4364 leaves us with 284.
Take the next digit (3) from the dividend and append it to 284, then repeat: 2843 / 816

Moving on to step 8:
2843 divided by 816 is 3 with a remainder of 395.
The number 3 becomes the next digit in our result. 
Result so far: 104153.0
If we take 2448 away from 2843, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 9:
816 goes into 3950 4 times with a remainder of 686.
The next digit of our result is 4. 
Result so far: 104153.4
The remainder is 686 after subtracting 3264 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Going ahead to step 10:
If we divide 6860 by 816, we get 8 and a remainder of 332.
Record the quotient 8 as the next digit in the result. 
Result so far: 104153.48
If we take 6528 away from 6860, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 11:
816 goes into 3320 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 104153.484
The remainder is 56 after subtracting 3264 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
The number 816 fits into 560 0 times, leaving a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 104153.484
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 13:
816 can be fit into 5600 6 times, resulting in a remainder of 704.
Put 6 as the next digit of the answer. 
Result so far: 104153.48406
Deduct 4896 from 5600 and we're left with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Moving on to step 14:
816 can be fit into 7040 8 times, resulting in a remainder of 512.
The next digit of our result is 8. 
Result so far: 104153.484068
Subtracting 6528 from 7040 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 15:
When dividing 5120 by 816, we get 6 with a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 104153.4840686
The remainder is 224 after subtracting 4896 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 16:
2240 divided by 816 is 2 with a remainder of 608.
Put 2 as the next digit of the answer. 
Result so far: 104153.48406862
If we subtract 1632 from 2240, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

The final outcome is 104153.48406862, with a leftover of 6.08e-07.
