99942129 ÷ 724 
We want to divide 99942129 by 724.

Going ahead to step 1:
The number 724 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 724

Let's proceed to step 2:
99 divided by 724 is 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Bring next digit (9) of the dividend behind the 99 and repeat the process: 999 / 724

Going ahead to step 3:
The number 724 fits into 999 1 times, leaving a remainder of 275.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 724 from 999 leaves us with 275.
Append the next digit (4) from the dividend to 275 and continue with: 2754 / 724

Advancing to step 4:
If we divide 2754 by 724, we get 3 and a remainder of 582.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 582 after subtracting 2172 from 2754.
Append the next digit (2) from the dividend to 582 and continue with: 5822 / 724

Step 5:
724 goes into 5822 8 times with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Subtracting 5792 from 5822 leaves us with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 724

Step 6:
301 divided by 724 is 0 with a remainder of 301.
Record the quotient 0 as the next digit in the result. 
Result so far: 1380.0
Subtracting 0 from 301 leaves us with 301.
Grab the next digit (2) from the dividend, add it to 301, then carry on: 3012 / 724

Step 7:
3012 divided by 724 is 4 with a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 13804.0
The remainder is 116 after subtracting 2896 from 3012.
Include the next digit (9) from the dividend after 116, then repeat: 1169 / 724

Let's proceed to step 8:
The number 724 fits into 1169 1 times, leaving a remainder of 445.
The number 1 becomes the next digit in our result. 
Result so far: 138041.0
If we take 724 away from 1169, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 9:
724 goes into 4450 6 times with a remainder of 106.
The number 6 becomes the next digit in our result. 
Result so far: 138041.6
If we take 4344 away from 4450, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 10:
724 can be fit into 1060 1 times, resulting in a remainder of 336.
Use 1 as the next digit of our solution. 
Result so far: 138041.61
The remainder is 336 after subtracting 724 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 11:
724 can be fit into 3360 4 times, resulting in a remainder of 464.
Use 4 as the next digit of our solution. 
Result so far: 138041.614
The remainder is 464 after subtracting 2896 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 12:
4640 divided by 724 is 6 with a remainder of 296.
The next digit of our result is 6. 
Result so far: 138041.6146
Deduct 4344 from 4640 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 13:
When dividing 2960 by 724, we get 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 138041.61464
Subtract 2896 from 2960 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
When dividing 640 by 724, we get 0 with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 138041.61464
Deduct 0 from 640 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 15:
When dividing 6400 by 724, we get 8 with a remainder of 608.
Use 8 as the next digit of our solution. 
Result so far: 138041.6146408
Deduct 5792 from 6400 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 16:
724 goes into 6080 8 times with a remainder of 288.
Put 8 as the next digit of the answer. 
Result so far: 138041.61464088
If we subtract 5792 from 6080, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The quotient of the division is 138041.61464088, and the remainder is 2.88e-07.
