Let's divide 21054129 by 443
Our goal is to divide 21054129 by 443.

Step 1:
443 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 443

Moving on to step 2:
If we divide 21 by 443, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 443

On to step 3:
443 can be fit into 210 0 times, resulting in 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 (5) from the dividend, attach it to 210 and continue: 2105 / 443

On to step 4:
The number 443 fits into 2105 4 times, leaving a remainder of 333.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 1772 away from 2105, we end up with 333.
Bring next digit (4) of the dividend behind the 333 and repeat the process: 3334 / 443

Step 5:
The number 443 fits into 3334 7 times, leaving a remainder of 233.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtract 3101 from 3334 to get 233.
Fetch the next digit (1) from the dividend, attach it to 233 and continue: 2331 / 443

Step 6:
443 can be fit into 2331 5 times, resulting in a remainder of 116.
Use 5 as the next digit of our solution. 
Result so far: 475.0
If we subtract 2215 from 2331, we get 116.
Grab the next digit (2) from the dividend, add it to 116, then carry on: 1162 / 443

Moving on to step 7:
If we divide 1162 by 443, we get 2 and a remainder of 276.
Write down 2 as next digit of the result. 
Result so far: 4752.0
Deduct 886 from 1162 and we're left with 276.
Bring next digit (9) of the dividend behind the 276 and repeat the process: 2769 / 443

Advancing to step 8:
When dividing 2769 by 443, we get 6 with a remainder of 111.
Write down 6 as next digit of the result. 
Result so far: 47526.0
Subtract 2658 from 2769 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 9:
443 goes into 1110 2 times with a remainder of 224.
The number 2 becomes the next digit in our result. 
Result so far: 47526.2
Subtract 886 from 1110 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 10:
The number 443 fits into 2240 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 47526.25
If we take 2215 away from 2240, we end up with 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 11:
The number 443 fits into 250 0 times, leaving a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 47526.25
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 12:
When dividing 2500 by 443, we get 5 with a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 47526.2505
Deduct 2215 from 2500 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 13:
443 can be fit into 2850 6 times, resulting in a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 47526.25056
Subtract 2658 from 2850 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 14:
If we divide 1920 by 443, we get 4 and a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 47526.250564
The remainder is 148 after subtracting 1772 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 15:
443 can be fit into 1480 3 times, resulting in a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 47526.2505643
Subtracting 1329 from 1480 leaves us with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 16:
1510 divided by 443 is 3 with a remainder of 181.
The number 3 becomes the next digit in our result. 
Result so far: 47526.25056433
If we subtract 1329 from 1510, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Our division results in 47526.25056433 with a remaining 1.81e-07.
