78393064 ÷ 203 
Our goal is to divide 78393064 by 203.

Moving on to step 1:
The number 203 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 203

Moving on to step 2:
203 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 203

Advancing to step 3:
203 goes into 783 3 times with a remainder of 174.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 609 from 783 leaves us with 174.
Bring next digit (9) of the dividend behind the 174 and repeat the process: 1749 / 203

Moving on to step 4:
1749 divided by 203 is 8 with a remainder of 125.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 1624 from 1749 to get 125.
Append the next digit (3) from the dividend to 125 and continue with: 1253 / 203

Advancing to step 5:
203 can be fit into 1253 6 times, resulting in a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 386.0
The remainder is 35 after subtracting 1218 from 1253.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 203

Advancing to step 6:
When dividing 350 by 203, we get 1 with a remainder of 147.
Write down 1 as next digit of the result. 
Result so far: 3861.0
Subtracting 203 from 350 leaves us with 147.
Bring next digit (6) of the dividend behind the 147 and repeat the process: 1476 / 203

Let's proceed to step 7:
203 can be fit into 1476 7 times, resulting in a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 38617.0
If we take 1421 away from 1476, we end up with 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 203

Advancing to step 8:
203 can be fit into 554 2 times, resulting in a remainder of 148.
Put 2 as the next digit of the answer. 
Result so far: 386172.0
If we take 406 away from 554, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 9:
203 can be fit into 1480 7 times, resulting in a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 386172.7
Deduct 1421 from 1480 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 10:
203 can be fit into 590 2 times, resulting in a remainder of 184.
Put 2 as the next digit of the answer. 
Result so far: 386172.72
Deduct 406 from 590 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 11:
When dividing 1840 by 203, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 386172.729
Subtracting 1827 from 1840 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
If we divide 130 by 203, we get 0 and a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 386172.729
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 13:
203 can be fit into 1300 6 times, resulting in a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 386172.72906
If we take 1218 away from 1300, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 14:
If we divide 820 by 203, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 386172.729064
Deduct 812 from 820 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 15:
If we divide 80 by 203, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 386172.729064
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
203 can be fit into 800 3 times, resulting in a remainder of 191.
Record the quotient 3 as the next digit in the result. 
Result so far: 386172.72906403
Deduct 609 from 800 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

In conclusion, the division gives 386172.72906403 with a balance of 1.91e-07.
