31029202 ÷ 407 
We're looking to find how many times 407 goes into 31029202.

Let's proceed to step 1:
If we divide 3 by 407, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
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 / 407

On to step 2:
31 divided by 407 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 407

Step 3:
The number 407 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 310 to get 310.
Fetch the next digit (2) from the dividend, attach it to 310 and continue: 3102 / 407

Advancing to step 4:
The number 407 fits into 3102 7 times, leaving a remainder of 253.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 2849 from 3102 to get 253.
Fetch the next digit (9) from the dividend, attach it to 253 and continue: 2539 / 407

Going ahead to step 5:
407 goes into 2539 6 times with a remainder of 97.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Deduct 2442 from 2539 and we're left with 97.
Fetch the next digit (2) from the dividend, attach it to 97 and continue: 972 / 407

Let's proceed to step 6:
407 can be fit into 972 2 times, resulting in a remainder of 158.
Use 2 as the next digit of our solution. 
Result so far: 762.0
Subtracting 814 from 972 leaves us with 158.
Bring next digit (0) of the dividend behind the 158 and repeat the process: 1580 / 407

Step 7:
The number 407 fits into 1580 3 times, leaving a remainder of 359.
Use 3 as the next digit of our solution. 
Result so far: 7623.0
The remainder is 359 after subtracting 1221 from 1580.
Bring next digit (2) of the dividend behind the 359 and repeat the process: 3592 / 407

Step 8:
407 can be fit into 3592 8 times, resulting in a remainder of 336.
The next digit of our result is 8. 
Result so far: 76238.0
Subtracting 3256 from 3592 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 9:
When dividing 3360 by 407, we get 8 with a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 76238.8
If we take 3256 away from 3360, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
When dividing 1040 by 407, we get 2 with a remainder of 226.
Use 2 as the next digit of our solution. 
Result so far: 76238.82
Subtracting 814 from 1040 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 11:
The number 407 fits into 2260 5 times, leaving a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 76238.825
Deduct 2035 from 2260 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 12:
2250 divided by 407 is 5 with a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 76238.8255
If we subtract 2035 from 2250, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

In conclusion, the division gives 76238.8255 with a balance of 0.00215.
