We're dividing 89191689 by 402 
Let's see how many times 402 fits into 89191689.

Moving on to step 1:
402 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 402

Going ahead to step 2:
402 goes into 89 0 times with a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Take the next digit (1) from the dividend and append it to 89, then repeat: 891 / 402

Moving on to step 3:
402 goes into 891 2 times with a remainder of 87.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 87 after subtracting 804 from 891.
Include the next digit (9) from the dividend after 87, then repeat: 879 / 402

Advancing to step 4:
When dividing 879 by 402, we get 2 with a remainder of 75.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 75 after subtracting 804 from 879.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 402

Step 5:
If we divide 751 by 402, we get 1 and a remainder of 349.
Use 1 as the next digit of our solution. 
Result so far: 221.0
Subtract 402 from 751 to get 349.
Take the next digit (6) from the dividend and append it to 349, then repeat: 3496 / 402

Step 6:
If we divide 3496 by 402, we get 8 and a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 2218.0
Subtracting 3216 from 3496 leaves us with 280.
Bring next digit (8) of the dividend behind the 280 and repeat the process: 2808 / 402

On to step 7:
If we divide 2808 by 402, we get 6 and a remainder of 396.
Put 6 as the next digit of the answer. 
Result so far: 22186.0
If we take 2412 away from 2808, we end up with 396.
Include the next digit (9) from the dividend after 396, then repeat: 3969 / 402

On to step 8:
402 goes into 3969 9 times with a remainder of 351.
Record the quotient 9 as the next digit in the result. 
Result so far: 221869.0
Deduct 3618 from 3969 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 9:
The number 402 fits into 3510 8 times, leaving a remainder of 294.
Use 8 as the next digit of our solution. 
Result so far: 221869.8
Subtract 3216 from 3510 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 10:
2940 divided by 402 is 7 with a remainder of 126.
The next digit of our result is 7. 
Result so far: 221869.87
The remainder is 126 after subtracting 2814 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 11:
1260 divided by 402 is 3 with a remainder of 54.
The next digit of our result is 3. 
Result so far: 221869.873
Subtract 1206 from 1260 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
When dividing 540 by 402, we get 1 with a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 221869.8731
Deduct 402 from 540 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 13:
When dividing 1380 by 402, we get 3 with a remainder of 174.
Write down 3 as next digit of the result. 
Result so far: 221869.87313
Subtracting 1206 from 1380 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 14:
402 can be fit into 1740 4 times, resulting in a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 221869.873134
If we subtract 1608 from 1740, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 15:
402 can be fit into 1320 3 times, resulting in a remainder of 114.
The number 3 becomes the next digit in our result. 
Result so far: 221869.8731343
Subtracting 1206 from 1320 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 16:
The number 402 fits into 1140 2 times, leaving a remainder of 336.
Use 2 as the next digit of our solution. 
Result so far: 221869.87313432
Subtracting 804 from 1140 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.

The final outcome is 221869.87313432, with a leftover of 3.36e-07.
