We're dividing 42957963 by 856 
We want to divide 42957963 by 856.

Let's proceed to step 1:
If we divide 4 by 856, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 856

Step 2:
The number 856 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 856

On to step 3:
856 goes into 429 0 times with a remainder of 429.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 429 after subtracting 0 from 429.
Fetch the next digit (5) from the dividend, attach it to 429 and continue: 4295 / 856

Advancing to step 4:
856 goes into 4295 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 4280 from 4295 leaves us with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 856

Advancing to step 5:
856 can be fit into 157 0 times, resulting in a remainder of 157.
The next digit of our result is 0. 
Result so far: 50.0
The remainder is 157 after subtracting 0 from 157.
Grab the next digit (9) from the dividend, add it to 157, then carry on: 1579 / 856

Going ahead to step 6:
856 can be fit into 1579 1 times, resulting in a remainder of 723.
Put 1 as the next digit of the answer. 
Result so far: 501.0
Deduct 856 from 1579 and we're left with 723.
Bring next digit (6) of the dividend behind the 723 and repeat the process: 7236 / 856

Advancing to step 7:
856 goes into 7236 8 times with a remainder of 388.
Write down 8 as next digit of the result. 
Result so far: 5018.0
If we take 6848 away from 7236, we end up with 388.
Fetch the next digit (3) from the dividend, attach it to 388 and continue: 3883 / 856

Advancing to step 8:
If we divide 3883 by 856, we get 4 and a remainder of 459.
The number 4 becomes the next digit in our result. 
Result so far: 50184.0
Deduct 3424 from 3883 and we're left with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

On to step 9:
If we divide 4590 by 856, we get 5 and a remainder of 310.
The next digit of our result is 5. 
Result so far: 50184.5
Subtract 4280 from 4590 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 10:
The number 856 fits into 3100 3 times, leaving a remainder of 532.
Put 3 as the next digit of the answer. 
Result so far: 50184.53
If we take 2568 away from 3100, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 11:
The number 856 fits into 5320 6 times, leaving a remainder of 184.
Use 6 as the next digit of our solution. 
Result so far: 50184.536
The remainder is 184 after subtracting 5136 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 12:
1840 divided by 856 is 2 with a remainder of 128.
The next digit of our result is 2. 
Result so far: 50184.5362
If we subtract 1712 from 1840, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 13:
The number 856 fits into 1280 1 times, leaving a remainder of 424.
Use 1 as the next digit of our solution. 
Result so far: 50184.53621
Subtract 856 from 1280 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 14:
856 goes into 4240 4 times with a remainder of 816.
Put 4 as the next digit of the answer. 
Result so far: 50184.536214
The remainder is 816 after subtracting 3424 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

On to step 15:
The number 856 fits into 8160 9 times, leaving a remainder of 456.
Record the quotient 9 as the next digit in the result. 
Result so far: 50184.5362149
If we subtract 7704 from 8160, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 16:
856 can be fit into 4560 5 times, resulting in a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 50184.53621495
The remainder is 280 after subtracting 4280 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

In conclusion, the division gives 50184.53621495 with a balance of 2.8e-07.
