42513151 ÷ 177 
We want to divide 42513151 by 177.

Step 1:
177 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 177

Going ahead to step 2:
If we divide 42 by 177, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 177

On to step 3:
The number 177 fits into 425 2 times, leaving a remainder of 71.
The next digit of our result is 2. 
Result so far: 2.0
If we take 354 away from 425, we end up with 71.
Take the next digit (1) from the dividend and append it to 71, then repeat: 711 / 177

Let's proceed to step 4:
If we divide 711 by 177, we get 4 and a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 708 away from 711, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 177

Step 5:
33 divided by 177 is 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 240.0
If we take 0 away from 33, we end up with 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 177

Going ahead to step 6:
331 divided by 177 is 1 with a remainder of 154.
The number 1 becomes the next digit in our result. 
Result so far: 2401.0
Subtract 177 from 331 to get 154.
Take the next digit (5) from the dividend and append it to 154, then repeat: 1545 / 177

Step 7:
177 goes into 1545 8 times with a remainder of 129.
The next digit of our result is 8. 
Result so far: 24018.0
Subtract 1416 from 1545 to get 129.
Bring next digit (1) of the dividend behind the 129 and repeat the process: 1291 / 177

Moving on to step 8:
177 goes into 1291 7 times with a remainder of 52.
The next digit of our result is 7. 
Result so far: 240187.0
Subtracting 1239 from 1291 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
When dividing 520 by 177, we get 2 with a remainder of 166.
The next digit of our result is 2. 
Result so far: 240187.2
Subtracting 354 from 520 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 10:
177 can be fit into 1660 9 times, resulting in a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 240187.29
Subtracting 1593 from 1660 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
670 divided by 177 is 3 with a remainder of 139.
Put 3 as the next digit of the answer. 
Result so far: 240187.293
If we take 531 away from 670, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 12:
177 goes into 1390 7 times with a remainder of 151.
The next digit of our result is 7. 
Result so far: 240187.2937
If we subtract 1239 from 1390, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 13:
If we divide 1510 by 177, we get 8 and a remainder of 94.
Record the quotient 8 as the next digit in the result. 
Result so far: 240187.29378
Subtract 1416 from 1510 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 14:
177 goes into 940 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 240187.293785
Subtract 885 from 940 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 15:
177 can be fit into 550 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 240187.2937853
Deduct 531 from 550 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 16:
190 divided by 177 is 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 240187.29378531
Subtracting 177 from 190 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.

Our division results in 240187.29378531 with a remaining 1.3e-08.
