69063503 divided by 858 
Our goal is to divide 69063503 by 858.

Let's proceed to step 1:
The number 858 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 858

Advancing to step 2:
69 divided by 858 is 0 with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 858

Going ahead to step 3:
858 goes into 690 0 times with a remainder of 690.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 690 to get 690.
Grab the next digit (6) from the dividend, add it to 690, then carry on: 6906 / 858

Let's proceed to step 4:
The number 858 fits into 6906 8 times, leaving a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 6864 from 6906 and we're left with 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 858

Advancing to step 5:
If we divide 423 by 858, we get 0 and a remainder of 423.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we take 0 away from 423, we end up with 423.
Append the next digit (5) from the dividend to 423 and continue with: 4235 / 858

On to step 6:
If we divide 4235 by 858, we get 4 and a remainder of 803.
The next digit of our result is 4. 
Result so far: 804.0
If we subtract 3432 from 4235, we get 803.
Bring next digit (0) of the dividend behind the 803 and repeat the process: 8030 / 858

Let's proceed to step 7:
If we divide 8030 by 858, we get 9 and a remainder of 308.
Put 9 as the next digit of the answer. 
Result so far: 8049.0
If we take 7722 away from 8030, we end up with 308.
Fetch the next digit (3) from the dividend, attach it to 308 and continue: 3083 / 858

On to step 8:
858 can be fit into 3083 3 times, resulting in a remainder of 509.
Put 3 as the next digit of the answer. 
Result so far: 80493.0
Subtract 2574 from 3083 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Moving on to step 9:
When dividing 5090 by 858, we get 5 with a remainder of 800.
The number 5 becomes the next digit in our result. 
Result so far: 80493.5
Subtract 4290 from 5090 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 10:
If we divide 8000 by 858, we get 9 and a remainder of 278.
The next digit of our result is 9. 
Result so far: 80493.59
Deduct 7722 from 8000 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 11:
If we divide 2780 by 858, we get 3 and a remainder of 206.
The number 3 becomes the next digit in our result. 
Result so far: 80493.593
Subtracting 2574 from 2780 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 12:
If we divide 2060 by 858, we get 2 and a remainder of 344.
The number 2 becomes the next digit in our result. 
Result so far: 80493.5932
If we subtract 1716 from 2060, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 13:
If we divide 3440 by 858, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 80493.59324
Subtracting 3432 from 3440 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
If we divide 80 by 858, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 80493.59324
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 15:
When dividing 800 by 858, we get 0 with a remainder of 800.
The next digit of our result is 0. 
Result so far: 80493.59324
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

After the division, we end up with 80493.59324 and a remainder of 8e-06.
