We're dividing 89086217 by 402 
We want to divide 89086217 by 402.

Step 1:
The number 402 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 402

Advancing to step 2:
89 divided by 402 is 0 with a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Take the next digit (0) from the dividend and append it to 89, then repeat: 890 / 402

Going ahead to step 3:
The number 402 fits into 890 2 times, leaving a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 804 from 890, we get 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 402

Step 4:
402 goes into 868 2 times with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 804 from 868 and we're left with 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 402

Step 5:
402 goes into 646 1 times with a remainder of 244.
Use 1 as the next digit of our solution. 
Result so far: 221.0
Deduct 402 from 646 and we're left with 244.
Take the next digit (2) from the dividend and append it to 244, then repeat: 2442 / 402

Let's proceed to step 6:
402 goes into 2442 6 times with a remainder of 30.
The next digit of our result is 6. 
Result so far: 2216.0
If we subtract 2412 from 2442, we get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 402

Advancing to step 7:
If we divide 301 by 402, we get 0 and a remainder of 301.
Put 0 as the next digit of the answer. 
Result so far: 22160.0
If we subtract 0 from 301, we get 301.
Grab the next digit (7) from the dividend, add it to 301, then carry on: 3017 / 402

Let's proceed to step 8:
If we divide 3017 by 402, we get 7 and a remainder of 203.
The next digit of our result is 7. 
Result so far: 221607.0
If we take 2814 away from 3017, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 9:
2030 divided by 402 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 221607.5
Subtract 2010 from 2030 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
When dividing 200 by 402, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 221607.5
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
2000 divided by 402 is 4 with a remainder of 392.
The next digit of our result is 4. 
Result so far: 221607.504
Deduct 1608 from 2000 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 12:
3920 divided by 402 is 9 with a remainder of 302.
Use 9 as the next digit of our solution. 
Result so far: 221607.5049
If we take 3618 away from 3920, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 13:
If we divide 3020 by 402, we get 7 and a remainder of 206.
Record the quotient 7 as the next digit in the result. 
Result so far: 221607.50497
If we subtract 2814 from 3020, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 14:
The number 402 fits into 2060 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 221607.504975
Subtracting 2010 from 2060 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
402 goes into 500 1 times with a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 221607.5049751
Deduct 402 from 500 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 16:
402 can be fit into 980 2 times, resulting in a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 221607.50497512
If we take 804 away from 980, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

In conclusion, the division gives 221607.50497512 with a balance of 1.76e-07.
