We look at the division of 42599946 by 310 
Our goal is to divide 42599946 by 310.

Advancing to step 1:
If we divide 4 by 310, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 310

On to step 2:
If we divide 42 by 310, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 310

Going ahead to step 3:
425 divided by 310 is 1 with a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 310 from 425 to get 115.
Append the next digit (9) from the dividend to 115 and continue with: 1159 / 310

Moving on to step 4:
If we divide 1159 by 310, we get 3 and a remainder of 229.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 930 from 1159 leaves us with 229.
Include the next digit (9) from the dividend after 229, then repeat: 2299 / 310

Going ahead to step 5:
The number 310 fits into 2299 7 times, leaving a remainder of 129.
Use 7 as the next digit of our solution. 
Result so far: 137.0
The remainder is 129 after subtracting 2170 from 2299.
Append the next digit (9) from the dividend to 129 and continue with: 1299 / 310

Advancing to step 6:
310 goes into 1299 4 times with a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 1374.0
If we subtract 1240 from 1299, we get 59.
Fetch the next digit (4) from the dividend, attach it to 59 and continue: 594 / 310

Step 7:
When dividing 594 by 310, we get 1 with a remainder of 284.
Use 1 as the next digit of our solution. 
Result so far: 13741.0
Deduct 310 from 594 and we're left with 284.
Grab the next digit (6) from the dividend, add it to 284, then carry on: 2846 / 310

Advancing to step 8:
310 can be fit into 2846 9 times, resulting in a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 137419.0
If we subtract 2790 from 2846, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
If we divide 560 by 310, we get 1 and a remainder of 250.
The next digit of our result is 1. 
Result so far: 137419.1
If we take 310 away from 560, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
2500 divided by 310 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 137419.18
If we subtract 2480 from 2500, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
The number 310 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 137419.18
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
When dividing 2000 by 310, we get 6 with a remainder of 140.
The number 6 becomes the next digit in our result. 
Result so far: 137419.1806
If we subtract 1860 from 2000, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
1400 divided by 310 is 4 with a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 137419.18064
Subtracting 1240 from 1400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
310 can be fit into 1600 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 137419.180645
If we take 1550 away from 1600, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 15:
If we divide 500 by 310, we get 1 and a remainder of 190.
Write down 1 as next digit of the result. 
Result so far: 137419.1806451
The remainder is 190 after subtracting 310 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 16:
310 can be fit into 1900 6 times, resulting in a remainder of 40.
The next digit of our result is 6. 
Result so far: 137419.18064516
Deduct 1860 from 1900 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 137419.18064516 with a remaining 4e-08.
