99773870 ÷ 104 
Our goal is to divide 99773870 by 104.

Advancing to step 1:
When dividing 9 by 104, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 104

Going ahead to step 2:
104 goes into 99 0 times with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 104

Advancing to step 3:
104 can be fit into 997 9 times, resulting in a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 936 from 997 to get 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 104

Step 4:
If we divide 617 by 104, we get 5 and a remainder of 97.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Deduct 520 from 617 and we're left with 97.
Take the next digit (3) from the dividend and append it to 97, then repeat: 973 / 104

Step 5:
973 divided by 104 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 959.0
Subtracting 936 from 973 leaves us with 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 104

Let's proceed to step 6:
378 divided by 104 is 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 9593.0
Subtracting 312 from 378 leaves us with 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 104

Step 7:
When dividing 667 by 104, we get 6 with a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 95936.0
Subtracting 624 from 667 leaves us with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 104

Going ahead to step 8:
104 can be fit into 430 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 959364.0
The remainder is 14 after subtracting 416 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
The number 104 fits into 140 1 times, leaving a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 959364.1
Subtracting 104 from 140 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
The number 104 fits into 360 3 times, leaving a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 959364.13
Deduct 312 from 360 and we're left 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.

Moving on to step 11:
When dividing 480 by 104, we get 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 959364.134
Subtracting 416 from 480 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
104 can be fit into 640 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 959364.1346
Deduct 624 from 640 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
104 can be fit into 160 1 times, resulting in a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 959364.13461
If we subtract 104 from 160, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
When dividing 560 by 104, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 959364.134615
If we subtract 520 from 560, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
If we divide 400 by 104, we get 3 and a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 959364.1346153
Subtract 312 from 400 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 16:
104 can be fit into 880 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 959364.13461538
Subtracting 832 from 880 leaves us 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.

The final result is 959364.13461538 with a remainder of 4.8e-08.
