78374993 ÷ 145 
We're looking to find how many times 145 goes into 78374993.

Going ahead to step 1:
145 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 145

Moving on to step 2:
The number 145 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 145

Advancing to step 3:
783 divided by 145 is 5 with a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 725 from 783 and we're left with 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 145

Let's proceed to step 4:
If we divide 587 by 145, we get 4 and a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 54.0
Deduct 580 from 587 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 145

Moving on to step 5:
145 goes into 74 0 times with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 540.0
The remainder is 74 after subtracting 0 from 74.
Include the next digit (9) from the dividend after 74, then repeat: 749 / 145

Let's proceed to step 6:
145 can be fit into 749 5 times, resulting in a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 5405.0
If we take 725 away from 749, we end up with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 145

Step 7:
When dividing 249 by 145, we get 1 with a remainder of 104.
Write down 1 as next digit of the result. 
Result so far: 54051.0
The remainder is 104 after subtracting 145 from 249.
Include the next digit (3) from the dividend after 104, then repeat: 1043 / 145

Step 8:
145 goes into 1043 7 times with a remainder of 28.
The next digit of our result is 7. 
Result so far: 540517.0
If we subtract 1015 from 1043, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
If we divide 280 by 145, we get 1 and a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 540517.1
The remainder is 135 after subtracting 145 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 10:
145 goes into 1350 9 times with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 540517.19
Subtract 1305 from 1350 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 11:
The number 145 fits into 450 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 540517.193
If we subtract 435 from 450, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
When dividing 150 by 145, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 540517.1931
Subtracting 145 from 150 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
145 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 540517.1931
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
If we divide 500 by 145, we get 3 and a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 540517.193103
If we subtract 435 from 500, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 15:
The number 145 fits into 650 4 times, leaving a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 540517.1931034
Subtracting 580 from 650 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 16:
145 goes into 700 4 times with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 540517.19310344
If we take 580 away from 700, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 540517.19310344 with a remainder of 1.2e-07.
