42659806 divided by 342 
Our goal is to divide 42659806 by 342.

Step 1:
342 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 342

Advancing to step 2:
The number 342 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 342

Let's proceed to step 3:
The number 342 fits into 426 1 times, leaving a remainder of 84.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 342 away from 426, we end up with 84.
Include the next digit (5) from the dividend after 84, then repeat: 845 / 342

Step 4:
845 divided by 342 is 2 with a remainder of 161.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 161 after subtracting 684 from 845.
Fetch the next digit (9) from the dividend, attach it to 161 and continue: 1619 / 342

Advancing to step 5:
If we divide 1619 by 342, we get 4 and a remainder of 251.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Deduct 1368 from 1619 and we're left with 251.
Take the next digit (8) from the dividend and append it to 251, then repeat: 2518 / 342

Let's proceed to step 6:
If we divide 2518 by 342, we get 7 and a remainder of 124.
Put 7 as the next digit of the answer. 
Result so far: 1247.0
The remainder is 124 after subtracting 2394 from 2518.
Fetch the next digit (0) from the dividend, attach it to 124 and continue: 1240 / 342

Advancing to step 7:
If we divide 1240 by 342, we get 3 and a remainder of 214.
Put 3 as the next digit of the answer. 
Result so far: 12473.0
If we take 1026 away from 1240, we end up with 214.
Grab the next digit (6) from the dividend, add it to 214, then carry on: 2146 / 342

Moving on to step 8:
If we divide 2146 by 342, we get 6 and a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 124736.0
Deduct 2052 from 2146 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 9:
342 goes into 940 2 times with a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 124736.2
If we take 684 away from 940, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 10:
342 can be fit into 2560 7 times, resulting in a remainder of 166.
Write down 7 as next digit of the result. 
Result so far: 124736.27
Subtract 2394 from 2560 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 11:
If we divide 1660 by 342, we get 4 and a remainder of 292.
The number 4 becomes the next digit in our result. 
Result so far: 124736.274
Subtract 1368 from 1660 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 12:
When dividing 2920 by 342, we get 8 with a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 124736.2748
Deduct 2736 from 2920 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 13:
If we divide 1840 by 342, we get 5 and a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 124736.27485
The remainder is 130 after subtracting 1710 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 14:
The number 342 fits into 1300 3 times, leaving a remainder of 274.
Write down 3 as next digit of the result. 
Result so far: 124736.274853
If we subtract 1026 from 1300, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 15:
2740 divided by 342 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 124736.2748538
If we take 2736 away from 2740, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 16:
342 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 124736.2748538
Subtracting 0 from 40 leaves us 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.

The final outcome is 124736.2748538, with a leftover of 4e-08.
