Let's divide 71229001 by 486
We want to divide 71229001 by 486.

Step 1:
If we divide 7 by 486, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 486

Advancing to step 2:
When dividing 71 by 486, we get 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 486

Going ahead to step 3:
486 goes into 712 1 times with a remainder of 226.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 486 from 712 and we're left with 226.
Fetch the next digit (2) from the dividend, attach it to 226 and continue: 2262 / 486

Going ahead to step 4:
If we divide 2262 by 486, we get 4 and a remainder of 318.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 318 after subtracting 1944 from 2262.
Append the next digit (9) from the dividend to 318 and continue with: 3189 / 486

Moving on to step 5:
486 goes into 3189 6 times with a remainder of 273.
Write down 6 as next digit of the result. 
Result so far: 146.0
The remainder is 273 after subtracting 2916 from 3189.
Bring next digit (0) of the dividend behind the 273 and repeat the process: 2730 / 486

Step 6:
2730 divided by 486 is 5 with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 1465.0
Subtract 2430 from 2730 to get 300.
Grab the next digit (0) from the dividend, add it to 300, then carry on: 3000 / 486

Advancing to step 7:
If we divide 3000 by 486, we get 6 and a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 14656.0
If we subtract 2916 from 3000, we get 84.
Bring next digit (1) of the dividend behind the 84 and repeat the process: 841 / 486

Advancing to step 8:
The number 486 fits into 841 1 times, leaving a remainder of 355.
The number 1 becomes the next digit in our result. 
Result so far: 146561.0
If we subtract 486 from 841, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 9:
486 goes into 3550 7 times with a remainder of 148.
Use 7 as the next digit of our solution. 
Result so far: 146561.7
Deduct 3402 from 3550 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 10:
486 goes into 1480 3 times with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 146561.73
The remainder is 22 after subtracting 1458 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
The number 486 fits into 220 0 times, leaving a remainder of 220.
The next digit of our result is 0. 
Result so far: 146561.73
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
486 goes into 2200 4 times with a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 146561.7304
The remainder is 256 after subtracting 1944 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 13:
When dividing 2560 by 486, we get 5 with a remainder of 130.
The next digit of our result is 5. 
Result so far: 146561.73045
If we take 2430 away from 2560, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 14:
486 goes into 1300 2 times with a remainder of 328.
The number 2 becomes the next digit in our result. 
Result so far: 146561.730452
Subtracting 972 from 1300 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 15:
486 goes into 3280 6 times with a remainder of 364.
Record the quotient 6 as the next digit in the result. 
Result so far: 146561.7304526
Subtracting 2916 from 3280 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 16:
486 can be fit into 3640 7 times, resulting in a remainder of 238.
Record the quotient 7 as the next digit in the result. 
Result so far: 146561.73045267
Subtracting 3402 from 3640 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The final outcome is 146561.73045267, with a leftover of 2.38e-07.
