31547681 ÷ 210 
We want to figure out the number of times 31547681 can be divided by 210.

Step 1:
3 divided by 210 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 210

Going ahead to step 2:
31 divided by 210 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 210

Let's proceed to step 3:
315 divided by 210 is 1 with a remainder of 105.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 210 from 315 leaves us with 105.
Bring next digit (4) of the dividend behind the 105 and repeat the process: 1054 / 210

Moving on to step 4:
The number 210 fits into 1054 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 1050 away from 1054, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 210

Going ahead to step 5:
210 can be fit into 47 0 times, resulting in a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtracting 0 from 47 leaves us with 47.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 210

Step 6:
The number 210 fits into 476 2 times, leaving a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 1502.0
The remainder is 56 after subtracting 420 from 476.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 210

On to step 7:
When dividing 568 by 210, we get 2 with a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 15022.0
If we take 420 away from 568, we end up with 148.
Fetch the next digit (1) from the dividend, attach it to 148 and continue: 1481 / 210

Let's proceed to step 8:
When dividing 1481 by 210, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 150227.0
If we subtract 1470 from 1481, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
The number 210 fits into 110 0 times, leaving a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 150227.0
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
1100 divided by 210 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 150227.05
The remainder is 50 after subtracting 1050 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
210 can be fit into 500 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 150227.052
If we subtract 420 from 500, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
210 can be fit into 800 3 times, resulting in a remainder of 170.
Write down 3 as next digit of the result. 
Result so far: 150227.0523
If we subtract 630 from 800, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 13:
1700 divided by 210 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 150227.05238
Subtracting 1680 from 1700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
200 divided by 210 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 150227.05238
If we subtract 0 from 200, 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.

Moving on to step 15:
210 goes into 2000 9 times with a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 150227.0523809
Subtracting 1890 from 2000 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 16:
210 goes into 1100 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 150227.05238095
Subtracting 1050 from 1100 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 150227.05238095 with a remaining 5e-08.
