42153702 ÷ 319 
We want to figure out the number of times 42153702 can be divided by 319.

On to step 1:
When dividing 4 by 319, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 319

Let's proceed to step 2:
319 goes into 42 0 times with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 319

Going ahead to step 3:
When dividing 421 by 319, we get 1 with a remainder of 102.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 319 from 421 leaves us with 102.
Append the next digit (5) from the dividend to 102 and continue with: 1025 / 319

Step 4:
The number 319 fits into 1025 3 times, leaving a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 957 from 1025 and we're left with 68.
Fetch the next digit (3) from the dividend, attach it to 68 and continue: 683 / 319

Let's proceed to step 5:
683 divided by 319 is 2 with a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Deduct 638 from 683 and we're left with 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 319

Let's proceed to step 6:
319 goes into 457 1 times with a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 1321.0
Subtracting 319 from 457 leaves us with 138.
Bring next digit (0) of the dividend behind the 138 and repeat the process: 1380 / 319

Let's proceed to step 7:
When dividing 1380 by 319, we get 4 with a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 13214.0
The remainder is 104 after subtracting 1276 from 1380.
Append the next digit (2) from the dividend to 104 and continue with: 1042 / 319

Moving on to step 8:
1042 divided by 319 is 3 with a remainder of 85.
Write down 3 as next digit of the result. 
Result so far: 132143.0
If we take 957 away from 1042, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
319 goes into 850 2 times with a remainder of 212.
The next digit of our result is 2. 
Result so far: 132143.2
Subtracting 638 from 850 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 10:
If we divide 2120 by 319, we get 6 and a remainder of 206.
The next digit of our result is 6. 
Result so far: 132143.26
Deduct 1914 from 2120 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 11:
319 can be fit into 2060 6 times, resulting in a remainder of 146.
Write down 6 as next digit of the result. 
Result so far: 132143.266
Subtracting 1914 from 2060 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

After the division, we end up with 132143.266 and a remainder of 0.0146.
