We divide 90541 by 21
Our goal is to divide 90541 by 21.

Let's proceed to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 21

Moving on to step 2:
21 goes into 90 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 84 from 90 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 21

Let's proceed to step 3:
21 can be fit into 65 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 2 after subtracting 63 from 65.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 21

Advancing to step 4:
21 can be fit into 24 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 431.0
Subtracting 21 from 24 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 21

Moving on to step 5:
If we divide 31 by 21, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 4311.0
The remainder is 10 after subtracting 21 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 6:
When dividing 100 by 21, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 4311.4
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
When dividing 160 by 21, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 4311.47
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 4311.476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 21 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 4311.4761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 4311.47619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
If we divide 10 by 21, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 4311.47619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 21, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4311.4761904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
If we divide 160 by 21, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 4311.47619047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 4311.47619047, and the remainder is 1.3e-08.
