Let's divide 97389559 by 215
We want to divide 97389559 by 215.

Let's proceed to step 1:
215 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 215

Let's proceed to step 2:
97 divided by 215 is 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Include the next digit (3) from the dividend after 97, then repeat: 973 / 215

On to step 3:
The number 215 fits into 973 4 times, leaving a remainder of 113.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 860 away from 973, we end up with 113.
Take the next digit (8) from the dividend and append it to 113, then repeat: 1138 / 215

On to step 4:
The number 215 fits into 1138 5 times, leaving a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 45.0
The remainder is 63 after subtracting 1075 from 1138.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 215

Going ahead to step 5:
The number 215 fits into 639 2 times, leaving a remainder of 209.
Record the quotient 2 as the next digit in the result. 
Result so far: 452.0
If we take 430 away from 639, we end up with 209.
Fetch the next digit (5) from the dividend, attach it to 209 and continue: 2095 / 215

Advancing to step 6:
215 can be fit into 2095 9 times, resulting in a remainder of 160.
Write down 9 as next digit of the result. 
Result so far: 4529.0
Subtract 1935 from 2095 to get 160.
Include the next digit (5) from the dividend after 160, then repeat: 1605 / 215

Step 7:
When dividing 1605 by 215, we get 7 with a remainder of 100.
Put 7 as the next digit of the answer. 
Result so far: 45297.0
If we subtract 1505 from 1605, we get 100.
Bring next digit (9) of the dividend behind the 100 and repeat the process: 1009 / 215

On to step 8:
1009 divided by 215 is 4 with a remainder of 149.
The next digit of our result is 4. 
Result so far: 452974.0
Subtract 860 from 1009 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 9:
The number 215 fits into 1490 6 times, leaving a remainder of 200.
The number 6 becomes the next digit in our result. 
Result so far: 452974.6
The remainder is 200 after subtracting 1290 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
If we divide 2000 by 215, we get 9 and a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 452974.69
Subtract 1935 from 2000 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
215 can be fit into 650 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 452974.693
Deduct 645 from 650 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
215 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 452974.693
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
215 can be fit into 500 2 times, resulting in a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 452974.69302
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 14:
215 goes into 700 3 times with a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 452974.693023
The remainder is 55 after subtracting 645 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 15:
When dividing 550 by 215, we get 2 with a remainder of 120.
The next digit of our result is 2. 
Result so far: 452974.6930232
If we take 430 away from 550, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 16:
215 can be fit into 1200 5 times, resulting in a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 452974.69302325
Deduct 1075 from 1200 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final outcome is 452974.69302325, with a leftover of 1.25e-07.
