We're dividing 99142573 by 586 
We want to figure out the number of times 99142573 can be divided by 586.

Moving on to step 1:
The number 586 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
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 / 586

Step 2:
99 divided by 586 is 0 with 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.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 586

Moving on to step 3:
991 divided by 586 is 1 with a remainder of 405.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 405 after subtracting 586 from 991.
Append the next digit (4) from the dividend to 405 and continue with: 4054 / 586

Let's proceed to step 4:
586 can be fit into 4054 6 times, resulting in a remainder of 538.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 3516 from 4054 and we're left with 538.
Include the next digit (2) from the dividend after 538, then repeat: 5382 / 586

Advancing to step 5:
5382 divided by 586 is 9 with a remainder of 108.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
Subtracting 5274 from 5382 leaves us with 108.
Take the next digit (5) from the dividend and append it to 108, then repeat: 1085 / 586

Step 6:
1085 divided by 586 is 1 with a remainder of 499.
Use 1 as the next digit of our solution. 
Result so far: 1691.0
Subtracting 586 from 1085 leaves us with 499.
Include the next digit (7) from the dividend after 499, then repeat: 4997 / 586

Advancing to step 7:
586 can be fit into 4997 8 times, resulting in a remainder of 309.
The number 8 becomes the next digit in our result. 
Result so far: 16918.0
If we subtract 4688 from 4997, we get 309.
Fetch the next digit (3) from the dividend, attach it to 309 and continue: 3093 / 586

Let's proceed to step 8:
The number 586 fits into 3093 5 times, leaving a remainder of 163.
The number 5 becomes the next digit in our result. 
Result so far: 169185.0
Deduct 2930 from 3093 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 9:
1630 divided by 586 is 2 with a remainder of 458.
Use 2 as the next digit of our solution. 
Result so far: 169185.2
Subtract 1172 from 1630 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 10:
586 can be fit into 4580 7 times, resulting in a remainder of 478.
The number 7 becomes the next digit in our result. 
Result so far: 169185.27
Subtracting 4102 from 4580 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 11:
586 can be fit into 4780 8 times, resulting in a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 169185.278
Deduct 4688 from 4780 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 12:
920 divided by 586 is 1 with a remainder of 334.
Put 1 as the next digit of the answer. 
Result so far: 169185.2781
Subtract 586 from 920 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 13:
When dividing 3340 by 586, we get 5 with a remainder of 410.
Put 5 as the next digit of the answer. 
Result so far: 169185.27815
If we subtract 2930 from 3340, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 14:
586 can be fit into 4100 6 times, resulting in a remainder of 584.
The next digit of our result is 6. 
Result so far: 169185.278156
The remainder is 584 after subtracting 3516 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 15:
586 goes into 5840 9 times with a remainder of 566.
Write down 9 as next digit of the result. 
Result so far: 169185.2781569
Deduct 5274 from 5840 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 16:
If we divide 5660 by 586, we get 9 and a remainder of 386.
Record the quotient 9 as the next digit in the result. 
Result so far: 169185.27815699
Subtract 5274 from 5660 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

After the division, we end up with 169185.27815699 and a remainder of 3.86e-07.
