87638334 ÷ 345 
We're looking to find how many times 345 goes into 87638334.

Let's proceed to step 1:
If we divide 8 by 345, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 345

Step 2:
If we divide 87 by 345, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Take the next digit (6) from the dividend and append it to 87, then repeat: 876 / 345

Advancing to step 3:
876 divided by 345 is 2 with a remainder of 186.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 690 from 876 leaves us with 186.
Take the next digit (3) from the dividend and append it to 186, then repeat: 1863 / 345

Moving on to step 4:
If we divide 1863 by 345, we get 5 and a remainder of 138.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 138 after subtracting 1725 from 1863.
Grab the next digit (8) from the dividend, add it to 138, then carry on: 1388 / 345

Let's proceed to step 5:
345 can be fit into 1388 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 254.0
Deduct 1380 from 1388 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 345

Moving on to step 6:
The number 345 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 2540.0
Deduct 0 from 83 and we're left with 83.
Bring next digit (3) of the dividend behind the 83 and repeat the process: 833 / 345

Let's proceed to step 7:
If we divide 833 by 345, we get 2 and a remainder of 143.
Write down 2 as next digit of the result. 
Result so far: 25402.0
Subtracting 690 from 833 leaves us with 143.
Include the next digit (4) from the dividend after 143, then repeat: 1434 / 345

Moving on to step 8:
If we divide 1434 by 345, we get 4 and a remainder of 54.
The next digit of our result is 4. 
Result so far: 254024.0
If we subtract 1380 from 1434, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
If we divide 540 by 345, we get 1 and a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 254024.1
Subtract 345 from 540 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 10:
345 goes into 1950 5 times with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 254024.15
If we take 1725 away from 1950, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 11:
345 goes into 2250 6 times with a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 254024.156
The remainder is 180 after subtracting 2070 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
345 can be fit into 1800 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 254024.1565
Deduct 1725 from 1800 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
If we divide 750 by 345, we get 2 and a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 254024.15652
If we subtract 690 from 750, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
The number 345 fits into 600 1 times, leaving a remainder of 255.
Use 1 as the next digit of our solution. 
Result so far: 254024.156521
Deduct 345 from 600 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 15:
345 can be fit into 2550 7 times, resulting in a remainder of 135.
Write down 7 as next digit of the result. 
Result so far: 254024.1565217
Deduct 2415 from 2550 and we're left 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.

Let's proceed to step 16:
345 can be fit into 1350 3 times, resulting in a remainder of 315.
The number 3 becomes the next digit in our result. 
Result so far: 254024.15652173
Subtract 1035 from 1350 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

In conclusion, the division gives 254024.15652173 with a balance of 3.15e-07.
