We divide 50999921 by 858
We're looking to find how many times 858 goes into 50999921.

Advancing to step 1:
The number 858 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 858

Let's proceed to step 2:
If we divide 50 by 858, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 858

On to step 3:
858 goes into 509 0 times with a remainder of 509.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 509, we end up with 509.
Take the next digit (9) from the dividend and append it to 509, then repeat: 5099 / 858

Step 4:
5099 divided by 858 is 5 with a remainder of 809.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 809 after subtracting 4290 from 5099.
Take the next digit (9) from the dividend and append it to 809, then repeat: 8099 / 858

Let's proceed to step 5:
The number 858 fits into 8099 9 times, leaving a remainder of 377.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtracting 7722 from 8099 leaves us with 377.
Take the next digit (9) from the dividend and append it to 377, then repeat: 3779 / 858

On to step 6:
If we divide 3779 by 858, we get 4 and a remainder of 347.
Put 4 as the next digit of the answer. 
Result so far: 594.0
Subtracting 3432 from 3779 leaves us with 347.
Grab the next digit (2) from the dividend, add it to 347, then carry on: 3472 / 858

Advancing to step 7:
When dividing 3472 by 858, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 5944.0
If we subtract 3432 from 3472, we get 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 858

Going ahead to step 8:
401 divided by 858 is 0 with a remainder of 401.
Record the quotient 0 as the next digit in the result. 
Result so far: 59440.0
If we take 0 away from 401, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 9:
When dividing 4010 by 858, we get 4 with a remainder of 578.
Write down 4 as next digit of the result. 
Result so far: 59440.4
If we take 3432 away from 4010, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

On to step 10:
5780 divided by 858 is 6 with a remainder of 632.
Use 6 as the next digit of our solution. 
Result so far: 59440.46
Deduct 5148 from 5780 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Step 11:
If we divide 6320 by 858, we get 7 and a remainder of 314.
Put 7 as the next digit of the answer. 
Result so far: 59440.467
If we subtract 6006 from 6320, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 12:
If we divide 3140 by 858, we get 3 and a remainder of 566.
The next digit of our result is 3. 
Result so far: 59440.4673
Deduct 2574 from 3140 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 13:
When dividing 5660 by 858, we get 6 with a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 59440.46736
Subtract 5148 from 5660 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 14:
The number 858 fits into 5120 5 times, leaving a remainder of 830.
Write down 5 as next digit of the result. 
Result so far: 59440.467365
If we take 4290 away from 5120, we end up with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Step 15:
When dividing 8300 by 858, we get 9 with a remainder of 578.
The number 9 becomes the next digit in our result. 
Result so far: 59440.4673659
If we take 7722 away from 8300, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Going ahead to step 16:
858 goes into 5780 6 times with a remainder of 632.
The next digit of our result is 6. 
Result so far: 59440.46736596
Subtract 5148 from 5780 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

The final result is 59440.46736596 with a remainder of 6.32e-07.
