Let's divide 42305378 by 313
We want to divide 42305378 by 313.

On to step 1:
4 divided by 313 is 0 with a remainder of 4.
The next digit of our result is 0. 
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 / 313

Moving on to step 2:
The number 313 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 313

Advancing to step 3:
313 goes into 423 1 times with a remainder of 110.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 313 from 423 leaves us with 110.
Take the next digit (0) from the dividend and append it to 110, then repeat: 1100 / 313

Let's proceed to step 4:
313 can be fit into 1100 3 times, resulting in a remainder of 161.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 939 away from 1100, we end up with 161.
Append the next digit (5) from the dividend to 161 and continue with: 1615 / 313

Step 5:
313 goes into 1615 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 135.0
If we subtract 1565 from 1615, we get 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 313

Moving on to step 6:
313 can be fit into 503 1 times, resulting in a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 1351.0
If we subtract 313 from 503, we get 190.
Fetch the next digit (7) from the dividend, attach it to 190 and continue: 1907 / 313

Going ahead to step 7:
313 can be fit into 1907 6 times, resulting in a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 13516.0
Deduct 1878 from 1907 and we're left with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 313

Going ahead to step 8:
If we divide 298 by 313, we get 0 and a remainder of 298.
Write down 0 as next digit of the result. 
Result so far: 135160.0
If we take 0 away from 298, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 9:
The number 313 fits into 2980 9 times, leaving a remainder of 163.
Record the quotient 9 as the next digit in the result. 
Result so far: 135160.9
Subtract 2817 from 2980 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 10:
313 goes into 1630 5 times with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 135160.95
The remainder is 65 after subtracting 1565 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 11:
313 can be fit into 650 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 135160.952
The remainder is 24 after subtracting 626 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
If we divide 240 by 313, we get 0 and a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 135160.952
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
The number 313 fits into 2400 7 times, leaving a remainder of 209.
Write down 7 as next digit of the result. 
Result so far: 135160.95207
Subtract 2191 from 2400 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 14:
313 can be fit into 2090 6 times, resulting in a remainder of 212.
The number 6 becomes the next digit in our result. 
Result so far: 135160.952076
If we subtract 1878 from 2090, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 15:
When dividing 2120 by 313, we get 6 with a remainder of 242.
Put 6 as the next digit of the answer. 
Result so far: 135160.9520766
Deduct 1878 from 2120 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final outcome is 135160.9520766, with a leftover of 2.42e-06.
