We divide 45860810 by 21
We want to divide 45860810 by 21.

On to step 1:
21 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 21

Going ahead to step 2:
45 divided by 21 is 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 42 from 45 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 21

Moving on to step 3:
When dividing 38 by 21, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 21 from 38 and we're left with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 21

Going ahead to step 4:
21 can be fit into 176 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 218.0
If we take 168 away from 176, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 21

Going ahead to step 5:
21 goes into 80 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 2183.0
If we subtract 63 from 80, we get 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 21

Step 6:
21 can be fit into 178 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 21838.0
Deduct 168 from 178 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 21

On to step 7:
When dividing 101 by 21, we get 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 218384.0
Deduct 84 from 101 and we're left with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 21

Advancing to step 8:
21 goes into 170 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 2183848.0
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.

Step 9:
When dividing 20 by 21, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2183848.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 2183848.09
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.

Step 11:
When dividing 110 by 21, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2183848.095
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.

Let's proceed to step 12:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2183848.0952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2183848.09523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
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: 2183848.095238
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.

Moving on to step 15:
20 divided by 21 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2183848.095238
If we subtract 0 from 20, we 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.

Step 16:
21 goes into 200 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 2183848.09523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 2183848.09523809, and the remainder is 1.1e-08.
