Let's divide 21873360 by 393
Our goal is to divide 21873360 by 393.

Advancing to step 1:
393 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 393

Step 2:
If we divide 21 by 393, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 393

Let's proceed to step 3:
393 can be fit into 218 0 times, resulting in a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 218 and we're left with 218.
Take the next digit (7) from the dividend and append it to 218, then repeat: 2187 / 393

Let's proceed to step 4:
393 can be fit into 2187 5 times, resulting in a remainder of 222.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 1965 from 2187 and we're left with 222.
Include the next digit (3) from the dividend after 222, then repeat: 2223 / 393

Let's proceed to step 5:
2223 divided by 393 is 5 with a remainder of 258.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Deduct 1965 from 2223 and we're left with 258.
Take the next digit (3) from the dividend and append it to 258, then repeat: 2583 / 393

Moving on to step 6:
2583 divided by 393 is 6 with a remainder of 225.
The number 6 becomes the next digit in our result. 
Result so far: 556.0
If we take 2358 away from 2583, we end up with 225.
Bring next digit (6) of the dividend behind the 225 and repeat the process: 2256 / 393

Advancing to step 7:
When dividing 2256 by 393, we get 5 with a remainder of 291.
Use 5 as the next digit of our solution. 
Result so far: 5565.0
Deduct 1965 from 2256 and we're left with 291.
Include the next digit (0) from the dividend after 291, then repeat: 2910 / 393

Moving on to step 8:
The number 393 fits into 2910 7 times, leaving a remainder of 159.
Use 7 as the next digit of our solution. 
Result so far: 55657.0
If we take 2751 away from 2910, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Let's proceed to step 9:
393 goes into 1590 4 times with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 55657.4
If we take 1572 away from 1590, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
180 divided by 393 is 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 55657.4
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
393 goes into 1800 4 times with a remainder of 228.
The next digit of our result is 4. 
Result so far: 55657.404
Subtracting 1572 from 1800 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 12:
The number 393 fits into 2280 5 times, leaving a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 55657.4045
Deduct 1965 from 2280 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 13:
When dividing 3150 by 393, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 55657.40458
Deduct 3144 from 3150 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
393 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 55657.40458
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
393 can be fit into 600 1 times, resulting in a remainder of 207.
The next digit of our result is 1. 
Result so far: 55657.4045801
Deduct 393 from 600 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 16:
393 can be fit into 2070 5 times, resulting in a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 55657.40458015
The remainder is 105 after subtracting 1965 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Our division results in 55657.40458015 with a remaining 1.05e-07.
