We're dividing 78154855 by 58 
Our goal is to divide 78154855 by 58.

Step 1:
When dividing 7 by 58, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 58

Step 2:
78 divided by 58 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 58 from 78 to get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 58

Moving on to step 3:
58 goes into 201 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 174 from 201 to get 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 58

Let's proceed to step 4:
The number 58 fits into 275 4 times, leaving a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 134.0
If we subtract 232 from 275, we get 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 58

On to step 5:
58 goes into 434 7 times with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 1347.0
If we take 406 away from 434, we end up with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 58

On to step 6:
58 can be fit into 288 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 13474.0
If we subtract 232 from 288, we get 56.
Append the next digit (5) from the dividend to 56 and continue with: 565 / 58

Going ahead to step 7:
The number 58 fits into 565 9 times, leaving a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 134749.0
Subtract 522 from 565 to get 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 58

Let's proceed to step 8:
58 can be fit into 435 7 times, resulting in a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 1347497.0
If we subtract 406 from 435, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
58 can be fit into 290 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1347497.5
Subtracting 290 from 290 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
58 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1347497.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
The number 58 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1347497.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1347497.5, with a leftover of 0.0.
