Let's see how many times 351 fits into 42134516.

On to step 1:
4 divided by 351 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 351

Step 2:
When dividing 42 by 351, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 351

Advancing to step 3:
The number 351 fits into 421 1 times, leaving a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 351 from 421 to get 70.
Grab the next digit (3) from the dividend, add it to 70, then carry on: 703 / 351

Moving on to step 4:
If we divide 703 by 351, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 702 from 703 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 351

Moving on to step 5:
14 divided by 351 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we take 0 away from 14, we end up with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 351

Advancing to step 6:
The number 351 fits into 145 0 times, leaving a remainder of 145.
The next digit of our result is 0. 
Result so far: 1200.0
Subtracting 0 from 145 leaves us with 145.
Include the next digit (1) from the dividend after 145, then repeat: 1451 / 351

On to step 7:
1451 divided by 351 is 4 with a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 12004.0
If we subtract 1404 from 1451, we get 47.
Fetch the next digit (6) from the dividend, attach it to 47 and continue: 476 / 351

Moving on to step 8:
476 divided by 351 is 1 with a remainder of 125.
Record the quotient 1 as the next digit in the result. 
Result so far: 120041.0
Subtracting 351 from 476 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 9:
351 goes into 1250 3 times with a remainder of 197.
The next digit of our result is 3. 
Result so far: 120041.3
The remainder is 197 after subtracting 1053 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 10:
351 goes into 1970 5 times with a remainder of 215.
The next digit of our result is 5. 
Result so far: 120041.35
Subtracting 1755 from 1970 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 11:
2150 divided by 351 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 120041.356
Subtracting 2106 from 2150 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
When dividing 440 by 351, we get 1 with a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 120041.3561
Subtract 351 from 440 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 13:
If we divide 890 by 351, we get 2 and a remainder of 188.
The next digit of our result is 2. 
Result so far: 120041.35612
If we take 702 away from 890, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 14:
351 goes into 1880 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 120041.356125
Deduct 1755 from 1880 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 15:
351 goes into 1250 3 times with a remainder of 197.
Use 3 as the next digit of our solution. 
Result so far: 120041.3561253
If we take 1053 away from 1250, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 16:
When dividing 1970 by 351, we get 5 with a remainder of 215.
The next digit of our result is 5. 
Result so far: 120041.35612535
The remainder is 215 after subtracting 1755 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

The final outcome is 120041.35612535, with a leftover of 2.15e-07.
