34650448 ÷ 851 
Our goal is to divide 34650448 by 851.

Step 1:
3 divided by 851 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 851

Going ahead to step 2:
The number 851 fits into 34 0 times, leaving a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 851

On to step 3:
346 divided by 851 is 0 with a remainder of 346.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 346 after subtracting 0 from 346.
Grab the next digit (5) from the dividend, add it to 346, then carry on: 3465 / 851

Advancing to step 4:
When dividing 3465 by 851, we get 4 with a remainder of 61.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3404 from 3465 leaves us with 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 851

Moving on to step 5:
If we divide 610 by 851, we get 0 and a remainder of 610.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Deduct 0 from 610 and we're left with 610.
Take the next digit (4) from the dividend and append it to 610, then repeat: 6104 / 851

On to step 6:
When dividing 6104 by 851, we get 7 with a remainder of 147.
Write down 7 as next digit of the result. 
Result so far: 407.0
Subtracting 5957 from 6104 leaves us with 147.
Bring next digit (4) of the dividend behind the 147 and repeat the process: 1474 / 851

Going ahead to step 7:
The number 851 fits into 1474 1 times, leaving a remainder of 623.
Put 1 as the next digit of the answer. 
Result so far: 4071.0
Subtract 851 from 1474 to get 623.
Fetch the next digit (8) from the dividend, attach it to 623 and continue: 6238 / 851

Going ahead to step 8:
The number 851 fits into 6238 7 times, leaving a remainder of 281.
Put 7 as the next digit of the answer. 
Result so far: 40717.0
If we take 5957 away from 6238, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 9:
851 can be fit into 2810 3 times, resulting in a remainder of 257.
Record the quotient 3 as the next digit in the result. 
Result so far: 40717.3
If we take 2553 away from 2810, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 10:
If we divide 2570 by 851, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 40717.33
Deduct 2553 from 2570 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 40717.33, with a leftover of 0.017.
