71666258 ÷ 406 
We want to divide 71666258 by 406.

Advancing to step 1:
If we divide 7 by 406, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 406

Advancing to step 2:
406 can be fit into 71 0 times, resulting in a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 406

Moving on to step 3:
If we divide 716 by 406, we get 1 and a remainder of 310.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 406 from 716 and we're left with 310.
Grab the next digit (6) from the dividend, add it to 310, then carry on: 3106 / 406

Going ahead to step 4:
406 goes into 3106 7 times with a remainder of 264.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 264 after subtracting 2842 from 3106.
Include the next digit (6) from the dividend after 264, then repeat: 2646 / 406

Moving on to step 5:
2646 divided by 406 is 6 with a remainder of 210.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
Deduct 2436 from 2646 and we're left with 210.
Grab the next digit (2) from the dividend, add it to 210, then carry on: 2102 / 406

Step 6:
The number 406 fits into 2102 5 times, leaving a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 1765.0
If we take 2030 away from 2102, we end up with 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 406

Advancing to step 7:
When dividing 725 by 406, we get 1 with a remainder of 319.
Use 1 as the next digit of our solution. 
Result so far: 17651.0
If we take 406 away from 725, we end up with 319.
Bring next digit (8) of the dividend behind the 319 and repeat the process: 3198 / 406

Going ahead to step 8:
406 goes into 3198 7 times with a remainder of 356.
Use 7 as the next digit of our solution. 
Result so far: 176517.0
If we take 2842 away from 3198, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 9:
If we divide 3560 by 406, we get 8 and a remainder of 312.
Put 8 as the next digit of the answer. 
Result so far: 176517.8
Subtract 3248 from 3560 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 10:
The number 406 fits into 3120 7 times, leaving a remainder of 278.
Put 7 as the next digit of the answer. 
Result so far: 176517.87
The remainder is 278 after subtracting 2842 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 11:
406 can be fit into 2780 6 times, resulting in a remainder of 344.
Record the quotient 6 as the next digit in the result. 
Result so far: 176517.876
The remainder is 344 after subtracting 2436 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 12:
If we divide 3440 by 406, we get 8 and a remainder of 192.
The next digit of our result is 8. 
Result so far: 176517.8768
Subtract 3248 from 3440 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 13:
406 can be fit into 1920 4 times, resulting in a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 176517.87684
If we take 1624 away from 1920, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 14:
406 goes into 2960 7 times with a remainder of 118.
Record the quotient 7 as the next digit in the result. 
Result so far: 176517.876847
Deduct 2842 from 2960 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 15:
If we divide 1180 by 406, we get 2 and a remainder of 368.
The number 2 becomes the next digit in our result. 
Result so far: 176517.8768472
Subtracting 812 from 1180 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 16:
406 can be fit into 3680 9 times, resulting in a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 176517.87684729
Subtracting 3654 from 3680 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 176517.87684729 with a balance of 2.6e-08.
