357 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 357

Advancing to step 2:
357 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 357

On to step 3:
357 goes into 125 0 times with a remainder of 125.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 125 to get 125.
Include the next digit (0) from the dividend after 125, then repeat: 1250 / 357

Advancing to step 4:
When dividing 1250 by 357, we get 3 with a remainder of 179.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1071 from 1250 leaves us with 179.
Grab the next digit (5) from the dividend, add it to 179, then carry on: 1795 / 357

Step 5:
357 goes into 1795 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 10 after subtracting 1785 from 1795.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 357

Step 6:
109 divided by 357 is 0 with a remainder of 109.
Write down 0 as next digit of the result. 
Result so far: 350.0
Deduct 0 from 109 and we're left with 109.
Fetch the next digit (5) from the dividend, attach it to 109 and continue: 1095 / 357

Advancing to step 7:
When dividing 1095 by 357, we get 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 3503.0
Subtract 1071 from 1095 to get 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 357

Moving on to step 8:
The number 357 fits into 248 0 times, leaving a remainder of 248.
The number 0 becomes the next digit in our result. 
Result so far: 35030.0
If we subtract 0 from 248, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 9:
357 goes into 2480 6 times with a remainder of 338.
Write down 6 as next digit of the result. 
Result so far: 35030.6
If we subtract 2142 from 2480, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 10:
If we divide 3380 by 357, we get 9 and a remainder of 167.
Use 9 as the next digit of our solution. 
Result so far: 35030.69
If we subtract 3213 from 3380, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

On to step 11:
If we divide 1670 by 357, we get 4 and a remainder of 242.
Put 4 as the next digit of the answer. 
Result so far: 35030.694
Subtracting 1428 from 1670 leaves us 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.

Step 12:
When dividing 2420 by 357, we get 6 with a remainder of 278.
Use 6 as the next digit of our solution. 
Result so far: 35030.6946
Deduct 2142 from 2420 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 13:
2780 divided by 357 is 7 with a remainder of 281.
Write down 7 as next digit of the result. 
Result so far: 35030.69467
If we subtract 2499 from 2780, we get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Let's proceed to step 14:
If we divide 2810 by 357, we get 7 and a remainder of 311.
The next digit of our result is 7. 
Result so far: 35030.694677
Subtracting 2499 from 2810 leaves us with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Our division results in 35030.694677 with a remaining 3.11e-05.
