77392473 ÷ 145 
Our goal is to divide 77392473 by 145.

Let's proceed to step 1:
When dividing 7 by 145, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 145

Moving on to step 2:
If we divide 77 by 145, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 145

Moving on to step 3:
When dividing 773 by 145, we get 5 with a remainder of 48.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 725 away from 773, we end up with 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 145

Let's proceed to step 4:
When dividing 489 by 145, we get 3 with a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtracting 435 from 489 leaves us with 54.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 145

Advancing to step 5:
If we divide 542 by 145, we get 3 and a remainder of 107.
The next digit of our result is 3. 
Result so far: 533.0
Subtract 435 from 542 to get 107.
Grab the next digit (4) from the dividend, add it to 107, then carry on: 1074 / 145

Advancing to step 6:
When dividing 1074 by 145, we get 7 with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 5337.0
Deduct 1015 from 1074 and we're left with 59.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 145

Advancing to step 7:
597 divided by 145 is 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 53374.0
Subtracting 580 from 597 leaves us with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 145

Advancing to step 8:
When dividing 173 by 145, we get 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 533741.0
Deduct 145 from 173 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
When dividing 280 by 145, we get 1 with a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 533741.1
Subtracting 145 from 280 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 10:
The number 145 fits into 1350 9 times, leaving a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 533741.19
If we take 1305 away from 1350, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
145 can be fit into 450 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 533741.193
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:
145 goes into 150 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 533741.1931
Deduct 145 from 150 and we're left 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.

Step 13:
If we divide 50 by 145, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 533741.1931
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
The number 145 fits into 500 3 times, leaving a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 533741.193103
If we take 435 away from 500, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 15:
145 goes into 650 4 times with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 533741.1931034
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.

On to step 16:
When dividing 700 by 145, we get 4 with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 533741.19310344
Subtract 580 from 700 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 533741.19310344 and a remainder of 1.2e-07.
