We're dividing 57458134 by 869 
We're looking to find how many times 869 goes into 57458134.

Moving on to step 1:
When dividing 5 by 869, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 869

Advancing to step 2:
57 divided by 869 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 869

Moving on to step 3:
574 divided by 869 is 0 with a remainder of 574.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 574 to get 574.
Grab the next digit (5) from the dividend, add it to 574, then carry on: 5745 / 869

Step 4:
869 goes into 5745 6 times with a remainder of 531.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 5214 from 5745 and we're left with 531.
Include the next digit (8) from the dividend after 531, then repeat: 5318 / 869

Moving on to step 5:
The number 869 fits into 5318 6 times, leaving a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Deduct 5214 from 5318 and we're left with 104.
Grab the next digit (1) from the dividend, add it to 104, then carry on: 1041 / 869

Advancing to step 6:
1041 divided by 869 is 1 with a remainder of 172.
The next digit of our result is 1. 
Result so far: 661.0
Deduct 869 from 1041 and we're left with 172.
Grab the next digit (3) from the dividend, add it to 172, then carry on: 1723 / 869

Let's proceed to step 7:
If we divide 1723 by 869, we get 1 and a remainder of 854.
The next digit of our result is 1. 
Result so far: 6611.0
Subtracting 869 from 1723 leaves us with 854.
Include the next digit (4) from the dividend after 854, then repeat: 8544 / 869

On to step 8:
If we divide 8544 by 869, we get 9 and a remainder of 723.
Use 9 as the next digit of our solution. 
Result so far: 66119.0
Subtract 7821 from 8544 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Let's proceed to step 9:
869 goes into 7230 8 times with a remainder of 278.
Write down 8 as next digit of the result. 
Result so far: 66119.8
Deduct 6952 from 7230 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 10:
869 goes into 2780 3 times with a remainder of 173.
Use 3 as the next digit of our solution. 
Result so far: 66119.83
Subtracting 2607 from 2780 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Advancing to step 11:
1730 divided by 869 is 1 with a remainder of 861.
The next digit of our result is 1. 
Result so far: 66119.831
If we take 869 away from 1730, we end up with 861.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8610, and continue the process.

Going ahead to step 12:
869 goes into 8610 9 times with a remainder of 789.
The number 9 becomes the next digit in our result. 
Result so far: 66119.8319
If we take 7821 away from 8610, we end up with 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Step 13:
7890 divided by 869 is 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 66119.83199
If we take 7821 away from 7890, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The quotient of the division is 66119.83199, and the remainder is 6.9e-05.
