86641830 ÷ 845 
We're looking to find how many times 845 goes into 86641830.

Moving on to step 1:
The number 845 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 845

Moving on to step 2:
The number 845 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 845

Step 3:
845 can be fit into 866 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 845 from 866 leaves us with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 845

Advancing to step 4:
If we divide 214 by 845, we get 0 and a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 214, we get 214.
Fetch the next digit (1) from the dividend, attach it to 214 and continue: 2141 / 845

Advancing to step 5:
2141 divided by 845 is 2 with a remainder of 451.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 1690 from 2141 to get 451.
Append the next digit (8) from the dividend to 451 and continue with: 4518 / 845

Advancing to step 6:
The number 845 fits into 4518 5 times, leaving a remainder of 293.
The next digit of our result is 5. 
Result so far: 1025.0
If we subtract 4225 from 4518, we get 293.
Take the next digit (3) from the dividend and append it to 293, then repeat: 2933 / 845

Moving on to step 7:
2933 divided by 845 is 3 with a remainder of 398.
Write down 3 as next digit of the result. 
Result so far: 10253.0
Subtracting 2535 from 2933 leaves us with 398.
Append the next digit (0) from the dividend to 398 and continue with: 3980 / 845

Let's proceed to step 8:
When dividing 3980 by 845, we get 4 with a remainder of 600.
Record the quotient 4 as the next digit in the result. 
Result so far: 102534.0
Subtract 3380 from 3980 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 9:
If we divide 6000 by 845, we get 7 and a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 102534.7
Subtracting 5915 from 6000 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 10:
845 can be fit into 850 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 102534.71
The remainder is 5 after subtracting 845 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
The number 845 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 102534.71
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
The number 845 fits into 500 0 times, leaving a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 102534.71
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 102534.71 with a remaining 0.005.
