We divide 42344728 by 345
We want to figure out the number of times 42344728 can be divided by 345.

Going ahead to step 1:
4 divided by 345 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 345

Going ahead to step 2:
When dividing 42 by 345, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 345

Step 3:
345 can be fit into 423 1 times, resulting in a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 78 after subtracting 345 from 423.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 345

Moving on to step 4:
If we divide 784 by 345, we get 2 and a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 690 from 784 to get 94.
Append the next digit (4) from the dividend to 94 and continue with: 944 / 345

Advancing to step 5:
The number 345 fits into 944 2 times, leaving a remainder of 254.
Use 2 as the next digit of our solution. 
Result so far: 122.0
The remainder is 254 after subtracting 690 from 944.
Bring next digit (7) of the dividend behind the 254 and repeat the process: 2547 / 345

On to step 6:
If we divide 2547 by 345, we get 7 and a remainder of 132.
Write down 7 as next digit of the result. 
Result so far: 1227.0
Subtract 2415 from 2547 to get 132.
Include the next digit (2) from the dividend after 132, then repeat: 1322 / 345

On to step 7:
345 can be fit into 1322 3 times, resulting in a remainder of 287.
Put 3 as the next digit of the answer. 
Result so far: 12273.0
If we subtract 1035 from 1322, we get 287.
Bring next digit (8) of the dividend behind the 287 and repeat the process: 2878 / 345

Let's proceed to step 8:
345 goes into 2878 8 times with a remainder of 118.
The number 8 becomes the next digit in our result. 
Result so far: 122738.0
Subtracting 2760 from 2878 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 9:
If we divide 1180 by 345, we get 3 and a remainder of 145.
Write down 3 as next digit of the result. 
Result so far: 122738.3
If we take 1035 away from 1180, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 10:
1450 divided by 345 is 4 with a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 122738.34
The remainder is 70 after subtracting 1380 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
345 goes into 700 2 times with a remainder of 10.
The next digit of our result is 2. 
Result so far: 122738.342
Deduct 690 from 700 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
100 divided by 345 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 122738.342
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
1000 divided by 345 is 2 with a remainder of 310.
Record the quotient 2 as the next digit in the result. 
Result so far: 122738.34202
If we subtract 690 from 1000, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 14:
When dividing 3100 by 345, we get 8 with a remainder of 340.
Use 8 as the next digit of our solution. 
Result so far: 122738.342028
If we take 2760 away from 3100, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 15:
When dividing 3400 by 345, we get 9 with a remainder of 295.
Write down 9 as next digit of the result. 
Result so far: 122738.3420289
If we subtract 3105 from 3400, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 16:
The number 345 fits into 2950 8 times, leaving a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 122738.34202898
Deduct 2760 from 2950 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

After the division, we end up with 122738.34202898 and a remainder of 1.9e-07.
