We look at the division of 21523133 by 131 
We're looking to find how many times 131 goes into 21523133.

On to step 1:
When dividing 2 by 131, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 131

On to step 2:
The number 131 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 131

Step 3:
The number 131 fits into 215 1 times, leaving a remainder of 84.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 84 after subtracting 131 from 215.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 131

Going ahead to step 4:
When dividing 842 by 131, we get 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 786 from 842 and we're left with 56.
Grab the next digit (3) from the dividend, add it to 56, then carry on: 563 / 131

Let's proceed to step 5:
563 divided by 131 is 4 with a remainder of 39.
The next digit of our result is 4. 
Result so far: 164.0
If we take 524 away from 563, we end up with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 131

Advancing to step 6:
If we divide 391 by 131, we get 2 and a remainder of 129.
Put 2 as the next digit of the answer. 
Result so far: 1642.0
Subtracting 262 from 391 leaves us with 129.
Append the next digit (3) from the dividend to 129 and continue with: 1293 / 131

Let's proceed to step 7:
131 goes into 1293 9 times with a remainder of 114.
Use 9 as the next digit of our solution. 
Result so far: 16429.0
If we subtract 1179 from 1293, we get 114.
Append the next digit (3) from the dividend to 114 and continue with: 1143 / 131

Let's proceed to step 8:
When dividing 1143 by 131, we get 8 with a remainder of 95.
Put 8 as the next digit of the answer. 
Result so far: 164298.0
If we subtract 1048 from 1143, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 9:
131 can be fit into 950 7 times, resulting in a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 164298.7
If we subtract 917 from 950, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
131 can be fit into 330 2 times, resulting in a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 164298.72
Deduct 262 from 330 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
131 goes into 680 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 164298.725
If we subtract 655 from 680, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
If we divide 250 by 131, we get 1 and a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 164298.7251
Subtract 131 from 250 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 13:
The number 131 fits into 1190 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 164298.72519
The remainder is 11 after subtracting 1179 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
When dividing 110 by 131, we get 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 164298.72519
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 15:
If we divide 1100 by 131, we get 8 and a remainder of 52.
The next digit of our result is 8. 
Result so far: 164298.7251908
If we subtract 1048 from 1100, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 16:
131 goes into 520 3 times with a remainder of 127.
Use 3 as the next digit of our solution. 
Result so far: 164298.72519083
Deduct 393 from 520 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Our division results in 164298.72519083 with a remaining 1.27e-07.
