We divide 2943599 by 856
We want to divide 2943599 by 856.

On to step 1:
2 divided by 856 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 856

Going ahead to step 2:
The number 856 fits into 29 0 times, leaving a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 856

On to step 3:
When dividing 294 by 856, we get 0 with a remainder of 294.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 294, we get 294.
Include the next digit (3) from the dividend after 294, then repeat: 2943 / 856

Let's proceed to step 4:
The number 856 fits into 2943 3 times, leaving a remainder of 375.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 375 after subtracting 2568 from 2943.
Bring next digit (5) of the dividend behind the 375 and repeat the process: 3755 / 856

Step 5:
When dividing 3755 by 856, we get 4 with a remainder of 331.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtract 3424 from 3755 to get 331.
Fetch the next digit (9) from the dividend, attach it to 331 and continue: 3319 / 856

Step 6:
The number 856 fits into 3319 3 times, leaving a remainder of 751.
The next digit of our result is 3. 
Result so far: 343.0
If we subtract 2568 from 3319, we get 751.
Grab the next digit (9) from the dividend, add it to 751, then carry on: 7519 / 856

On to step 7:
When dividing 7519 by 856, we get 8 with a remainder of 671.
Put 8 as the next digit of the answer. 
Result so far: 3438.0
Subtracting 6848 from 7519 leaves us with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Let's proceed to step 8:
6710 divided by 856 is 7 with a remainder of 718.
The next digit of our result is 7. 
Result so far: 3438.7
Subtract 5992 from 6710 to get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

On to step 9:
856 can be fit into 7180 8 times, resulting in a remainder of 332.
Use 8 as the next digit of our solution. 
Result so far: 3438.78
If we take 6848 away from 7180, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Let's proceed to step 10:
If we divide 3320 by 856, we get 3 and a remainder of 752.
Put 3 as the next digit of the answer. 
Result so far: 3438.783
If we subtract 2568 from 3320, we get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Going ahead to step 11:
856 can be fit into 7520 8 times, resulting in a remainder of 672.
Use 8 as the next digit of our solution. 
Result so far: 3438.7838
If we take 6848 away from 7520, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Advancing to step 12:
856 goes into 6720 7 times with a remainder of 728.
Record the quotient 7 as the next digit in the result. 
Result so far: 3438.78387
If we take 5992 away from 6720, we end up with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

On to step 13:
If we divide 7280 by 856, we get 8 and a remainder of 432.
Write down 8 as next digit of the result. 
Result so far: 3438.783878
Subtracting 6848 from 7280 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 14:
If we divide 4320 by 856, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 3438.7838785
The remainder is 40 after subtracting 4280 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
856 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 3438.7838785
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 3438.7838785, with a leftover of 4e-07.
