We're dividing 2135293 by 345 
Our goal is to divide 2135293 by 345.

Advancing to step 1:
When dividing 2 by 345, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 345

Step 2:
The number 345 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 345

Moving on to step 3:
The number 345 fits into 213 0 times, leaving a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Take the next digit (5) from the dividend and append it to 213, then repeat: 2135 / 345

Advancing to step 4:
If we divide 2135 by 345, we get 6 and a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 2070 from 2135 leaves us with 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 345

Step 5:
When dividing 652 by 345, we get 1 with a remainder of 307.
The next digit of our result is 1. 
Result so far: 61.0
If we subtract 345 from 652, we get 307.
Fetch the next digit (9) from the dividend, attach it to 307 and continue: 3079 / 345

On to step 6:
3079 divided by 345 is 8 with a remainder of 319.
Write down 8 as next digit of the result. 
Result so far: 618.0
Deduct 2760 from 3079 and we're left with 319.
Fetch the next digit (3) from the dividend, attach it to 319 and continue: 3193 / 345

Advancing to step 7:
If we divide 3193 by 345, we get 9 and a remainder of 88.
Put 9 as the next digit of the answer. 
Result so far: 6189.0
Subtract 3105 from 3193 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 8:
345 goes into 880 2 times with a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 6189.2
If we subtract 690 from 880, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 9:
If we divide 1900 by 345, we get 5 and a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 6189.25
Deduct 1725 from 1900 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 10:
345 goes into 1750 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6189.255
Subtracting 1725 from 1750 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.

After the division, we end up with 6189.255 and a remainder of 0.0025.
