80537745 ÷ 858 
Our goal is to divide 80537745 by 858.

Advancing to step 1:
If we divide 8 by 858, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 858

Moving on to step 2:
80 divided by 858 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 858

Step 3:
805 divided by 858 is 0 with a remainder of 805.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 805, we get 805.
Fetch the next digit (3) from the dividend, attach it to 805 and continue: 8053 / 858

Let's proceed to step 4:
8053 divided by 858 is 9 with a remainder of 331.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 7722 from 8053 and we're left with 331.
Grab the next digit (7) from the dividend, add it to 331, then carry on: 3317 / 858

Going ahead to step 5:
If we divide 3317 by 858, we get 3 and a remainder of 743.
The next digit of our result is 3. 
Result so far: 93.0
Subtract 2574 from 3317 to get 743.
Fetch the next digit (7) from the dividend, attach it to 743 and continue: 7437 / 858

Going ahead to step 6:
The number 858 fits into 7437 8 times, leaving a remainder of 573.
Put 8 as the next digit of the answer. 
Result so far: 938.0
The remainder is 573 after subtracting 6864 from 7437.
Bring next digit (4) of the dividend behind the 573 and repeat the process: 5734 / 858

On to step 7:
5734 divided by 858 is 6 with a remainder of 586.
Record the quotient 6 as the next digit in the result. 
Result so far: 9386.0
Subtract 5148 from 5734 to get 586.
Grab the next digit (5) from the dividend, add it to 586, then carry on: 5865 / 858

Step 8:
5865 divided by 858 is 6 with a remainder of 717.
The number 6 becomes the next digit in our result. 
Result so far: 93866.0
Subtracting 5148 from 5865 leaves us with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Step 9:
If we divide 7170 by 858, we get 8 and a remainder of 306.
Record the quotient 8 as the next digit in the result. 
Result so far: 93866.8
The remainder is 306 after subtracting 6864 from 7170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 10:
3060 divided by 858 is 3 with a remainder of 486.
The next digit of our result is 3. 
Result so far: 93866.83
If we subtract 2574 from 3060, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 11:
When dividing 4860 by 858, we get 5 with a remainder of 570.
The number 5 becomes the next digit in our result. 
Result so far: 93866.835
Deduct 4290 from 4860 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 12:
858 goes into 5700 6 times with a remainder of 552.
The next digit of our result is 6. 
Result so far: 93866.8356
If we subtract 5148 from 5700, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 13:
5520 divided by 858 is 6 with a remainder of 372.
The number 6 becomes the next digit in our result. 
Result so far: 93866.83566
If we subtract 5148 from 5520, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

In conclusion, the division gives 93866.83566 with a balance of 0.000372.
