99889732 ÷ 773 
Our goal is to divide 99889732 by 773.

Let's proceed to step 1:
If we divide 9 by 773, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 773

On to step 2:
If we divide 99 by 773, we get 0 and a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Bring next digit (8) of the dividend behind the 99 and repeat the process: 998 / 773

Advancing to step 3:
When dividing 998 by 773, we get 1 with a remainder of 225.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 773 from 998 leaves us with 225.
Include the next digit (8) from the dividend after 225, then repeat: 2258 / 773

Step 4:
773 goes into 2258 2 times with a remainder of 712.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1546 away from 2258, we end up with 712.
Fetch the next digit (9) from the dividend, attach it to 712 and continue: 7129 / 773

Let's proceed to step 5:
7129 divided by 773 is 9 with a remainder of 172.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtracting 6957 from 7129 leaves us with 172.
Grab the next digit (7) from the dividend, add it to 172, then carry on: 1727 / 773

Step 6:
773 can be fit into 1727 2 times, resulting in a remainder of 181.
Record the quotient 2 as the next digit in the result. 
Result so far: 1292.0
Subtracting 1546 from 1727 leaves us with 181.
Take the next digit (3) from the dividend and append it to 181, then repeat: 1813 / 773

Advancing to step 7:
If we divide 1813 by 773, we get 2 and a remainder of 267.
Write down 2 as next digit of the result. 
Result so far: 12922.0
If we subtract 1546 from 1813, we get 267.
Fetch the next digit (2) from the dividend, attach it to 267 and continue: 2672 / 773

Going ahead to step 8:
773 goes into 2672 3 times with a remainder of 353.
The next digit of our result is 3. 
Result so far: 129223.0
Deduct 2319 from 2672 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Let's proceed to step 9:
If we divide 3530 by 773, we get 4 and a remainder of 438.
The next digit of our result is 4. 
Result so far: 129223.4
If we subtract 3092 from 3530, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Let's proceed to step 10:
773 can be fit into 4380 5 times, resulting in a remainder of 515.
Write down 5 as next digit of the result. 
Result so far: 129223.45
If we take 3865 away from 4380, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Going ahead to step 11:
773 goes into 5150 6 times with a remainder of 512.
Put 6 as the next digit of the answer. 
Result so far: 129223.456
If we subtract 4638 from 5150, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 12:
773 can be fit into 5120 6 times, resulting in a remainder of 482.
Use 6 as the next digit of our solution. 
Result so far: 129223.4566
The remainder is 482 after subtracting 4638 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

The final result is 129223.4566 with a remainder of 0.00482.
