Append the next digit (5) from the dividend to 1 and continue with: 15 / 355

Advancing to step 2:
The number 355 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 355

Advancing to step 3:
If we divide 159 by 355, we get 0 and a remainder of 159.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 159 to get 159.
Append the next digit (1) from the dividend to 159 and continue with: 1591 / 355

Step 4:
When dividing 1591 by 355, we get 4 with a remainder of 171.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1420 from 1591 to get 171.
Fetch the next digit (9) from the dividend, attach it to 171 and continue: 1719 / 355

Moving on to step 5:
355 goes into 1719 4 times with a remainder of 299.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 1420 from 1719 to get 299.
Fetch the next digit (4) from the dividend, attach it to 299 and continue: 2994 / 355

Moving on to step 6:
2994 divided by 355 is 8 with a remainder of 154.
Record the quotient 8 as the next digit in the result. 
Result so far: 448.0
The remainder is 154 after subtracting 2840 from 2994.
Fetch the next digit (2) from the dividend, attach it to 154 and continue: 1542 / 355

On to step 7:
If we divide 1542 by 355, we get 4 and a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 4484.0
Deduct 1420 from 1542 and we're left with 122.
Take the next digit (5) from the dividend and append it to 122, then repeat: 1225 / 355

On to step 8:
The number 355 fits into 1225 3 times, leaving a remainder of 160.
Record the quotient 3 as the next digit in the result. 
Result so far: 44843.0
Subtracting 1065 from 1225 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.

Advancing to step 9:
1600 divided by 355 is 4 with a remainder of 180.
The next digit of our result is 4. 
Result so far: 44843.4
If we take 1420 away from 1600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
The number 355 fits into 1800 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 44843.45
Subtracting 1775 from 1800 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
When dividing 250 by 355, we get 0 with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 44843.45
The remainder is 250 after subtracting 0 from 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 12:
2500 divided by 355 is 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 44843.4507
Deduct 2485 from 2500 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
When dividing 150 by 355, we get 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 44843.4507
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 14:
355 can be fit into 1500 4 times, resulting in a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 44843.450704
Deduct 1420 from 1500 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 15:
If we divide 800 by 355, we get 2 and a remainder of 90.
The next digit of our result is 2. 
Result so far: 44843.4507042
Subtracting 710 from 800 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 16:
900 divided by 355 is 2 with a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 44843.45070422
Subtracting 710 from 900 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final outcome is 44843.45070422, with a leftover of 1.9e-07.
