We're dividing 97790974 by 215 
We're looking to find how many times 215 goes into 97790974.

Step 1:
The number 215 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 215

Advancing to step 2:
215 can be fit into 97 0 times, resulting in a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Take the next digit (7) from the dividend and append it to 97, then repeat: 977 / 215

Step 3:
The number 215 fits into 977 4 times, leaving a remainder of 117.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 860 away from 977, we end up with 117.
Grab the next digit (9) from the dividend, add it to 117, then carry on: 1179 / 215

Moving on to step 4:
1179 divided by 215 is 5 with a remainder of 104.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Deduct 1075 from 1179 and we're left with 104.
Bring next digit (0) of the dividend behind the 104 and repeat the process: 1040 / 215

Moving on to step 5:
When dividing 1040 by 215, we get 4 with a remainder of 180.
Write down 4 as next digit of the result. 
Result so far: 454.0
Deduct 860 from 1040 and we're left with 180.
Append the next digit (9) from the dividend to 180 and continue with: 1809 / 215

On to step 6:
When dividing 1809 by 215, we get 8 with a remainder of 89.
The next digit of our result is 8. 
Result so far: 4548.0
Deduct 1720 from 1809 and we're left with 89.
Take the next digit (7) from the dividend and append it to 89, then repeat: 897 / 215

Step 7:
897 divided by 215 is 4 with a remainder of 37.
The next digit of our result is 4. 
Result so far: 45484.0
The remainder is 37 after subtracting 860 from 897.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 215

On to step 8:
215 can be fit into 374 1 times, resulting in a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 454841.0
The remainder is 159 after subtracting 215 from 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Let's proceed to step 9:
When dividing 1590 by 215, we get 7 with a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 454841.7
Deduct 1505 from 1590 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 10:
215 can be fit into 850 3 times, resulting in a remainder of 205.
Use 3 as the next digit of our solution. 
Result so far: 454841.73
Subtracting 645 from 850 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 11:
215 goes into 2050 9 times with a remainder of 115.
Write down 9 as next digit of the result. 
Result so far: 454841.739
If we subtract 1935 from 2050, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 12:
1150 divided by 215 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 454841.7395
Subtract 1075 from 1150 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
When dividing 750 by 215, we get 3 with a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 454841.73953
If we subtract 645 from 750, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 14:
1050 divided by 215 is 4 with a remainder of 190.
The number 4 becomes the next digit in our result. 
Result so far: 454841.739534
Subtracting 860 from 1050 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 15:
If we divide 1900 by 215, we get 8 and a remainder of 180.
Write down 8 as next digit of the result. 
Result so far: 454841.7395348
The remainder is 180 after subtracting 1720 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 16:
215 goes into 1800 8 times with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 454841.73953488
Subtract 1720 from 1800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 454841.73953488 and a remainder of 8e-08.
