Let's divide 90209015 by 158
Our goal is to divide 90209015 by 158.

Let's proceed to step 1:
9 divided by 158 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 158

Let's proceed to step 2:
If we divide 90 by 158, we get 0 and a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 158

Advancing to step 3:
If we divide 902 by 158, we get 5 and a remainder of 112.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 790 from 902 to get 112.
Take the next digit (0) from the dividend and append it to 112, then repeat: 1120 / 158

Going ahead to step 4:
The number 158 fits into 1120 7 times, leaving a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
If we take 1106 away from 1120, we end up with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 158

Let's proceed to step 5:
When dividing 149 by 158, we get 0 with a remainder of 149.
Record the quotient 0 as the next digit in the result. 
Result so far: 570.0
If we take 0 away from 149, we end up with 149.
Fetch the next digit (0) from the dividend, attach it to 149 and continue: 1490 / 158

Going ahead to step 6:
If we divide 1490 by 158, we get 9 and a remainder of 68.
The next digit of our result is 9. 
Result so far: 5709.0
If we take 1422 away from 1490, we end up with 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 158

Advancing to step 7:
158 goes into 681 4 times with a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 57094.0
The remainder is 49 after subtracting 632 from 681.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 158

Advancing to step 8:
495 divided by 158 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 570943.0
If we subtract 474 from 495, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
158 goes into 210 1 times with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 570943.1
If we take 158 away from 210, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
When dividing 520 by 158, we get 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 570943.13
Deduct 474 from 520 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
158 can be fit into 460 2 times, resulting in a remainder of 144.
The next digit of our result is 2. 
Result so far: 570943.132
Subtracting 316 from 460 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 12:
If we divide 1440 by 158, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 570943.1329
If we subtract 1422 from 1440, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
When dividing 180 by 158, we get 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 570943.13291
Subtract 158 from 180 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
158 goes into 220 1 times with a remainder of 62.
The next digit of our result is 1. 
Result so far: 570943.132911
If we subtract 158 from 220, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 570943.132911, with a leftover of 6.2e-06.
