We're dividing 31453473 by 850 
We want to divide 31453473 by 850.

Let's proceed to step 1:
The number 850 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 850

Step 2:
31 divided by 850 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 850

Moving on to step 3:
850 can be fit into 314 0 times, resulting in a remainder of 314.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 314 leaves us with 314.
Append the next digit (5) from the dividend to 314 and continue with: 3145 / 850

Going ahead to step 4:
When dividing 3145 by 850, we get 3 with a remainder of 595.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 595 after subtracting 2550 from 3145.
Append the next digit (3) from the dividend to 595 and continue with: 5953 / 850

Step 5:
The number 850 fits into 5953 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we take 5950 away from 5953, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 850

Advancing to step 6:
If we divide 34 by 850, we get 0 and a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 370.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 850

Step 7:
If we divide 347 by 850, we get 0 and a remainder of 347.
Write down 0 as next digit of the result. 
Result so far: 3700.0
The remainder is 347 after subtracting 0 from 347.
Take the next digit (3) from the dividend and append it to 347, then repeat: 3473 / 850

On to step 8:
850 can be fit into 3473 4 times, resulting in a remainder of 73.
Use 4 as the next digit of our solution. 
Result so far: 37004.0
If we subtract 3400 from 3473, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 9:
850 goes into 730 0 times with a remainder of 730.
The next digit of our result is 0. 
Result so far: 37004.0
Deduct 0 from 730 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 10:
850 can be fit into 7300 8 times, resulting in a remainder of 500.
Put 8 as the next digit of the answer. 
Result so far: 37004.08
Deduct 6800 from 7300 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 11:
850 can be fit into 5000 5 times, resulting in a remainder of 750.
Use 5 as the next digit of our solution. 
Result so far: 37004.085
Deduct 4250 from 5000 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Let's proceed to step 12:
The number 850 fits into 7500 8 times, leaving a remainder of 700.
The number 8 becomes the next digit in our result. 
Result so far: 37004.0858
The remainder is 700 after subtracting 6800 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 13:
When dividing 7000 by 850, we get 8 with a remainder of 200.
Put 8 as the next digit of the answer. 
Result so far: 37004.08588
If we subtract 6800 from 7000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 37004.08588 and a remainder of 0.0002.
