21248394 ÷ 593 
Our goal is to divide 21248394 by 593.

Moving on to step 1:
593 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 593

Going ahead to step 2:
When dividing 21 by 593, we get 0 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.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 593

Going ahead to step 3:
The number 593 fits into 212 0 times, leaving a remainder of 212.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 212, we get 212.
Fetch the next digit (4) from the dividend, attach it to 212 and continue: 2124 / 593

Step 4:
If we divide 2124 by 593, we get 3 and a remainder of 345.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1779 from 2124 and we're left with 345.
Take the next digit (8) from the dividend and append it to 345, then repeat: 3458 / 593

On to step 5:
593 goes into 3458 5 times with a remainder of 493.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we subtract 2965 from 3458, we get 493.
Take the next digit (3) from the dividend and append it to 493, then repeat: 4933 / 593

Let's proceed to step 6:
If we divide 4933 by 593, we get 8 and a remainder of 189.
The number 8 becomes the next digit in our result. 
Result so far: 358.0
If we take 4744 away from 4933, we end up with 189.
Grab the next digit (9) from the dividend, add it to 189, then carry on: 1899 / 593

Step 7:
1899 divided by 593 is 3 with a remainder of 120.
The next digit of our result is 3. 
Result so far: 3583.0
If we subtract 1779 from 1899, we get 120.
Take the next digit (4) from the dividend and append it to 120, then repeat: 1204 / 593

On to step 8:
The number 593 fits into 1204 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 35832.0
Subtract 1186 from 1204 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
When dividing 180 by 593, we get 0 with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 35832.0
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.

Let's proceed to step 10:
The number 593 fits into 1800 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 35832.03
Deduct 1779 from 1800 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.

Advancing to step 11:
593 can be fit into 210 0 times, resulting in a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 35832.03
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 12:
593 can be fit into 2100 3 times, resulting in a remainder of 321.
Put 3 as the next digit of the answer. 
Result so far: 35832.0303
Subtracting 1779 from 2100 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 13:
If we divide 3210 by 593, we get 5 and a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 35832.03035
If we subtract 2965 from 3210, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 14:
If we divide 2450 by 593, we get 4 and a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 35832.030354
Deduct 2372 from 2450 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 15:
593 can be fit into 780 1 times, resulting in a remainder of 187.
Write down 1 as next digit of the result. 
Result so far: 35832.0303541
If we take 593 away from 780, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 16:
593 goes into 1870 3 times with a remainder of 91.
The next digit of our result is 3. 
Result so far: 35832.03035413
If we take 1779 away from 1870, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

The final outcome is 35832.03035413, with a leftover of 9.1e-08.
