Let's divide 56966219 by 858
We want to divide 56966219 by 858.

On to step 1:
858 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 858

Moving on to step 2:
56 divided by 858 is 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 858

Moving on to step 3:
569 divided by 858 is 0 with a remainder of 569.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 569 leaves us with 569.
Fetch the next digit (6) from the dividend, attach it to 569 and continue: 5696 / 858

On to step 4:
The number 858 fits into 5696 6 times, leaving a remainder of 548.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 5148 from 5696, we get 548.
Bring next digit (6) of the dividend behind the 548 and repeat the process: 5486 / 858

Step 5:
858 can be fit into 5486 6 times, resulting in a remainder of 338.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtracting 5148 from 5486 leaves us with 338.
Include the next digit (2) from the dividend after 338, then repeat: 3382 / 858

Step 6:
The number 858 fits into 3382 3 times, leaving a remainder of 808.
The number 3 becomes the next digit in our result. 
Result so far: 663.0
The remainder is 808 after subtracting 2574 from 3382.
Include the next digit (1) from the dividend after 808, then repeat: 8081 / 858

Advancing to step 7:
The number 858 fits into 8081 9 times, leaving a remainder of 359.
Put 9 as the next digit of the answer. 
Result so far: 6639.0
If we subtract 7722 from 8081, we get 359.
Append the next digit (9) from the dividend to 359 and continue with: 3599 / 858

Going ahead to step 8:
858 can be fit into 3599 4 times, resulting in a remainder of 167.
The next digit of our result is 4. 
Result so far: 66394.0
Deduct 3432 from 3599 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 9:
If we divide 1670 by 858, we get 1 and a remainder of 812.
The number 1 becomes the next digit in our result. 
Result so far: 66394.1
The remainder is 812 after subtracting 858 from 1670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

On to step 10:
The number 858 fits into 8120 9 times, leaving a remainder of 398.
Put 9 as the next digit of the answer. 
Result so far: 66394.19
The remainder is 398 after subtracting 7722 from 8120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 11:
If we divide 3980 by 858, we get 4 and a remainder of 548.
The next digit of our result is 4. 
Result so far: 66394.194
If we take 3432 away from 3980, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Moving on to step 12:
If we divide 5480 by 858, we get 6 and a remainder of 332.
Put 6 as the next digit of the answer. 
Result so far: 66394.1946
The remainder is 332 after subtracting 5148 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 13:
858 can be fit into 3320 3 times, resulting in a remainder of 746.
Put 3 as the next digit of the answer. 
Result so far: 66394.19463
Deduct 2574 from 3320 and we're left with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Step 14:
7460 divided by 858 is 8 with a remainder of 596.
Use 8 as the next digit of our solution. 
Result so far: 66394.194638
If we take 6864 away from 7460, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 15:
If we divide 5960 by 858, we get 6 and a remainder of 812.
The number 6 becomes the next digit in our result. 
Result so far: 66394.1946386
Deduct 5148 from 5960 and we're left with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Moving on to step 16:
8120 divided by 858 is 9 with a remainder of 398.
Use 9 as the next digit of our solution. 
Result so far: 66394.19463869
If we subtract 7722 from 8120, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

The final outcome is 66394.19463869, with a leftover of 3.98e-07.
