78420848 ÷ 593 
Our goal is to divide 78420848 by 593.

Going ahead to step 1:
593 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 593

Advancing to step 2:
78 divided by 593 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 593

Moving on to step 3:
593 can be fit into 784 1 times, resulting in a remainder of 191.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 191 after subtracting 593 from 784.
Bring next digit (2) of the dividend behind the 191 and repeat the process: 1912 / 593

Advancing to step 4:
The number 593 fits into 1912 3 times, leaving a remainder of 133.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1779 from 1912 leaves us with 133.
Take the next digit (0) from the dividend and append it to 133, then repeat: 1330 / 593

Advancing to step 5:
593 can be fit into 1330 2 times, resulting in a remainder of 144.
Use 2 as the next digit of our solution. 
Result so far: 132.0
The remainder is 144 after subtracting 1186 from 1330.
Grab the next digit (8) from the dividend, add it to 144, then carry on: 1448 / 593

Step 6:
593 goes into 1448 2 times with a remainder of 262.
Write down 2 as next digit of the result. 
Result so far: 1322.0
If we take 1186 away from 1448, we end up with 262.
Include the next digit (4) from the dividend after 262, then repeat: 2624 / 593

Advancing to step 7:
When dividing 2624 by 593, we get 4 with a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 13224.0
The remainder is 252 after subtracting 2372 from 2624.
Include the next digit (8) from the dividend after 252, then repeat: 2528 / 593

On to step 8:
2528 divided by 593 is 4 with a remainder of 156.
Write down 4 as next digit of the result. 
Result so far: 132244.0
If we subtract 2372 from 2528, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 9:
1560 divided by 593 is 2 with a remainder of 374.
The next digit of our result is 2. 
Result so far: 132244.2
Deduct 1186 from 1560 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 10:
593 can be fit into 3740 6 times, resulting in a remainder of 182.
Put 6 as the next digit of the answer. 
Result so far: 132244.26
Subtracting 3558 from 3740 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 11:
If we divide 1820 by 593, we get 3 and a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 132244.263
Deduct 1779 from 1820 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 12:
593 can be fit into 410 0 times, resulting in a remainder of 410.
Write down 0 as next digit of the result. 
Result so far: 132244.263
Deduct 0 from 410 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 13:
593 goes into 4100 6 times with a remainder of 542.
Write down 6 as next digit of the result. 
Result so far: 132244.26306
Deduct 3558 from 4100 and we're left with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Moving on to step 14:
If we divide 5420 by 593, we get 9 and a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 132244.263069
Deduct 5337 from 5420 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 15:
593 goes into 830 1 times with a remainder of 237.
The next digit of our result is 1. 
Result so far: 132244.2630691
Deduct 593 from 830 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 16:
593 can be fit into 2370 3 times, resulting in a remainder of 591.
Put 3 as the next digit of the answer. 
Result so far: 132244.26306913
The remainder is 591 after subtracting 1779 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

The final outcome is 132244.26306913, with a leftover of 5.91e-07.
