31870452 ÷ 149 
Let's see how many times 149 fits into 31870452.

Moving on to step 1:
When dividing 3 by 149, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 149

Moving on to step 2:
149 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 149

Step 3:
The number 149 fits into 318 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 298 from 318, we get 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 149

Moving on to step 4:
149 goes into 207 1 times with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 58 after subtracting 149 from 207.
Take the next digit (0) from the dividend and append it to 58, then repeat: 580 / 149

Step 5:
When dividing 580 by 149, we get 3 with a remainder of 133.
The next digit of our result is 3. 
Result so far: 213.0
If we subtract 447 from 580, we get 133.
Bring next digit (4) of the dividend behind the 133 and repeat the process: 1334 / 149

Step 6:
149 goes into 1334 8 times with a remainder of 142.
Write down 8 as next digit of the result. 
Result so far: 2138.0
Deduct 1192 from 1334 and we're left with 142.
Fetch the next digit (5) from the dividend, attach it to 142 and continue: 1425 / 149

On to step 7:
If we divide 1425 by 149, we get 9 and a remainder of 84.
Record the quotient 9 as the next digit in the result. 
Result so far: 21389.0
Subtracting 1341 from 1425 leaves us with 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 149

Let's proceed to step 8:
The number 149 fits into 842 5 times, leaving a remainder of 97.
The next digit of our result is 5. 
Result so far: 213895.0
Deduct 745 from 842 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
If we divide 970 by 149, we get 6 and a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 213895.6
If we subtract 894 from 970, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
760 divided by 149 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 213895.65
Subtracting 745 from 760 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
If we divide 150 by 149, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 213895.651
If we take 149 away from 150, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
The number 149 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 213895.651
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
When dividing 100 by 149, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 213895.651
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 213895.651 with a balance of 0.0001.
