41091425 ÷ 21 
We want to divide 41091425 by 21.

Step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 21

Step 2:
The number 21 fits into 41 1 times, leaving a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
If we take 21 away from 41, we end up with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 21

Going ahead to step 3:
21 goes into 200 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 189 from 200 and we're left with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 21

On to step 4:
The number 21 fits into 119 5 times, leaving a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
If we take 105 away from 119, we end up with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 21

Step 5:
The number 21 fits into 141 6 times, leaving a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 1956.0
The remainder is 15 after subtracting 126 from 141.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 21

Going ahead to step 6:
21 can be fit into 154 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 19567.0
If we take 147 away from 154, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 21

On to step 7:
If we divide 72 by 21, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 195673.0
Deduct 63 from 72 and we're left with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 21

Step 8:
95 divided by 21 is 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 1956734.0
If we take 84 away from 95, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1956734.5
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1956734.52
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 1956734.523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
If we divide 170 by 21, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 1956734.5238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
20 divided by 21 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 1956734.5238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
When dividing 200 by 21, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1956734.523809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 15:
When dividing 110 by 21, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1956734.5238095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 16:
21 goes into 50 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 1956734.52380952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 1956734.52380952 with a remaining 8e-09.
