We're dividing 21002079 by 481 
Our goal is to divide 21002079 by 481.

Let's proceed to step 1:
481 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 481

On to step 2:
481 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 481

Step 3:
If we divide 210 by 481, we get 0 and a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Fetch the next digit (0) from the dividend, attach it to 210 and continue: 2100 / 481

On to step 4:
481 can be fit into 2100 4 times, resulting in a remainder of 176.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 1924 away from 2100, we end up with 176.
Append the next digit (2) from the dividend to 176 and continue with: 1762 / 481

Step 5:
The number 481 fits into 1762 3 times, leaving a remainder of 319.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtract 1443 from 1762 to get 319.
Bring next digit (0) of the dividend behind the 319 and repeat the process: 3190 / 481

On to step 6:
481 can be fit into 3190 6 times, resulting in a remainder of 304.
Put 6 as the next digit of the answer. 
Result so far: 436.0
The remainder is 304 after subtracting 2886 from 3190.
Grab the next digit (7) from the dividend, add it to 304, then carry on: 3047 / 481

Going ahead to step 7:
481 can be fit into 3047 6 times, resulting in a remainder of 161.
Use 6 as the next digit of our solution. 
Result so far: 4366.0
If we subtract 2886 from 3047, we get 161.
Grab the next digit (9) from the dividend, add it to 161, then carry on: 1619 / 481

Moving on to step 8:
When dividing 1619 by 481, we get 3 with a remainder of 176.
Put 3 as the next digit of the answer. 
Result so far: 43663.0
Deduct 1443 from 1619 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 9:
The number 481 fits into 1760 3 times, leaving a remainder of 317.
Record the quotient 3 as the next digit in the result. 
Result so far: 43663.3
If we subtract 1443 from 1760, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 10:
The number 481 fits into 3170 6 times, leaving a remainder of 284.
Use 6 as the next digit of our solution. 
Result so far: 43663.36
If we subtract 2886 from 3170, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 11:
481 can be fit into 2840 5 times, resulting in a remainder of 435.
Use 5 as the next digit of our solution. 
Result so far: 43663.365
If we subtract 2405 from 2840, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Let's proceed to step 12:
The number 481 fits into 4350 9 times, leaving a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 43663.3659
Deduct 4329 from 4350 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
When dividing 210 by 481, we get 0 with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 43663.3659
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 14:
If we divide 2100 by 481, we get 4 and a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 43663.365904
The remainder is 176 after subtracting 1924 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 15:
1760 divided by 481 is 3 with a remainder of 317.
Put 3 as the next digit of the answer. 
Result so far: 43663.3659043
The remainder is 317 after subtracting 1443 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 16:
If we divide 3170 by 481, we get 6 and a remainder of 284.
Use 6 as the next digit of our solution. 
Result so far: 43663.36590436
The remainder is 284 after subtracting 2886 from 3170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

In conclusion, the division gives 43663.36590436 with a balance of 2.84e-07.
