57455098 ÷ 834 
We want to figure out the number of times 57455098 can be divided by 834.

Step 1:
If we divide 5 by 834, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 834

On to step 2:
57 divided by 834 is 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Fetch the next digit (4) from the dividend, attach it to 57 and continue: 574 / 834

Let's proceed to step 3:
The number 834 fits into 574 0 times, leaving a remainder of 574.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 574, we end up with 574.
Take the next digit (5) from the dividend and append it to 574, then repeat: 5745 / 834

Advancing to step 4:
If we divide 5745 by 834, we get 6 and a remainder of 741.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 5004 from 5745 leaves us with 741.
Fetch the next digit (5) from the dividend, attach it to 741 and continue: 7415 / 834

On to step 5:
834 goes into 7415 8 times with a remainder of 743.
The next digit of our result is 8. 
Result so far: 68.0
Subtracting 6672 from 7415 leaves us with 743.
Append the next digit (0) from the dividend to 743 and continue with: 7430 / 834

Moving on to step 6:
7430 divided by 834 is 8 with a remainder of 758.
Record the quotient 8 as the next digit in the result. 
Result so far: 688.0
Subtract 6672 from 7430 to get 758.
Bring next digit (9) of the dividend behind the 758 and repeat the process: 7589 / 834

On to step 7:
834 goes into 7589 9 times with a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 6889.0
Subtracting 7506 from 7589 leaves us with 83.
Grab the next digit (8) from the dividend, add it to 83, then carry on: 838 / 834

On to step 8:
The number 834 fits into 838 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 68891.0
Subtracting 834 from 838 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
When dividing 40 by 834, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 68891.0
Subtract 0 from 40 to get 40.
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 10:
If we divide 400 by 834, we get 0 and a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 68891.0
Deduct 0 from 400 and we're left with 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 result is 68891.0 with a remainder of 0.4.
