We divide 99154211 by 721
We're looking to find how many times 721 goes into 99154211.

On to step 1:
721 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 721

Advancing to step 2:
If we divide 99 by 721, we get 0 and a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Take the next digit (1) from the dividend and append it to 99, then repeat: 991 / 721

On to step 3:
If we divide 991 by 721, we get 1 and a remainder of 270.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 721 from 991 and we're left with 270.
Bring next digit (5) of the dividend behind the 270 and repeat the process: 2705 / 721

Going ahead to step 4:
721 goes into 2705 3 times with a remainder of 542.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 2163 from 2705 to get 542.
Fetch the next digit (4) from the dividend, attach it to 542 and continue: 5424 / 721

Advancing to step 5:
The number 721 fits into 5424 7 times, leaving a remainder of 377.
Write down 7 as next digit of the result. 
Result so far: 137.0
Subtract 5047 from 5424 to get 377.
Grab the next digit (2) from the dividend, add it to 377, then carry on: 3772 / 721

Advancing to step 6:
The number 721 fits into 3772 5 times, leaving a remainder of 167.
Record the quotient 5 as the next digit in the result. 
Result so far: 1375.0
Subtract 3605 from 3772 to get 167.
Grab the next digit (1) from the dividend, add it to 167, then carry on: 1671 / 721

Step 7:
1671 divided by 721 is 2 with a remainder of 229.
The next digit of our result is 2. 
Result so far: 13752.0
Subtract 1442 from 1671 to get 229.
Fetch the next digit (1) from the dividend, attach it to 229 and continue: 2291 / 721

Going ahead to step 8:
If we divide 2291 by 721, we get 3 and a remainder of 128.
Record the quotient 3 as the next digit in the result. 
Result so far: 137523.0
Subtract 2163 from 2291 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 9:
1280 divided by 721 is 1 with a remainder of 559.
Put 1 as the next digit of the answer. 
Result so far: 137523.1
The remainder is 559 after subtracting 721 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Let's proceed to step 10:
721 can be fit into 5590 7 times, resulting in a remainder of 543.
Put 7 as the next digit of the answer. 
Result so far: 137523.17
If we subtract 5047 from 5590, we get 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Advancing to step 11:
721 can be fit into 5430 7 times, resulting in a remainder of 383.
Put 7 as the next digit of the answer. 
Result so far: 137523.177
Subtract 5047 from 5430 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

The final result is 137523.177 with a remainder of 0.0383.
