69040445 ÷ 858 
We want to figure out the number of times 69040445 can be divided by 858.

On to step 1:
858 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 858

Going ahead to step 2:
858 goes into 69 0 times with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 858

Advancing to step 3:
858 goes into 690 0 times with a remainder of 690.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 690, we end up with 690.
Include the next digit (4) from the dividend after 690, then repeat: 6904 / 858

Advancing to step 4:
When dividing 6904 by 858, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 6864 from 6904, we get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 858

Going ahead to step 5:
If we divide 400 by 858, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we take 0 away from 400, we end up with 400.
Append the next digit (4) from the dividend to 400 and continue with: 4004 / 858

On to step 6:
If we divide 4004 by 858, we get 4 and a remainder of 572.
Record the quotient 4 as the next digit in the result. 
Result so far: 804.0
The remainder is 572 after subtracting 3432 from 4004.
Fetch the next digit (4) from the dividend, attach it to 572 and continue: 5724 / 858

Step 7:
When dividing 5724 by 858, we get 6 with a remainder of 576.
The next digit of our result is 6. 
Result so far: 8046.0
Deduct 5148 from 5724 and we're left with 576.
Grab the next digit (5) from the dividend, add it to 576, then carry on: 5765 / 858

Step 8:
If we divide 5765 by 858, we get 6 and a remainder of 617.
Put 6 as the next digit of the answer. 
Result so far: 80466.0
If we take 5148 away from 5765, we end up with 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Going ahead to step 9:
If we divide 6170 by 858, we get 7 and a remainder of 164.
Put 7 as the next digit of the answer. 
Result so far: 80466.7
Subtract 6006 from 6170 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 10:
858 can be fit into 1640 1 times, resulting in a remainder of 782.
Use 1 as the next digit of our solution. 
Result so far: 80466.71
Subtracting 858 from 1640 leaves us with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Moving on to step 11:
7820 divided by 858 is 9 with a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 80466.719
Deduct 7722 from 7820 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 12:
When dividing 980 by 858, we get 1 with a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 80466.7191
If we take 858 away from 980, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 13:
The number 858 fits into 1220 1 times, leaving a remainder of 362.
The number 1 becomes the next digit in our result. 
Result so far: 80466.71911
If we take 858 away from 1220, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

In conclusion, the division gives 80466.71911 with a balance of 0.000362.
