86621472 ÷ 217 
Let's see how many times 217 fits into 86621472.

Step 1:
217 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 217

Advancing to step 2:
217 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 217

Advancing to step 3:
866 divided by 217 is 3 with a remainder of 215.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 651 from 866, we get 215.
Include the next digit (2) from the dividend after 215, then repeat: 2152 / 217

On to step 4:
When dividing 2152 by 217, we get 9 with a remainder of 199.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 1953 from 2152, we get 199.
Grab the next digit (1) from the dividend, add it to 199, then carry on: 1991 / 217

Moving on to step 5:
217 goes into 1991 9 times with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 399.0
Subtracting 1953 from 1991 leaves us with 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 217

On to step 6:
217 goes into 384 1 times with a remainder of 167.
Use 1 as the next digit of our solution. 
Result so far: 3991.0
Subtracting 217 from 384 leaves us with 167.
Include the next digit (7) from the dividend after 167, then repeat: 1677 / 217

Going ahead to step 7:
1677 divided by 217 is 7 with a remainder of 158.
The number 7 becomes the next digit in our result. 
Result so far: 39917.0
Deduct 1519 from 1677 and we're left with 158.
Grab the next digit (2) from the dividend, add it to 158, then carry on: 1582 / 217

On to step 8:
1582 divided by 217 is 7 with a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 399177.0
Subtracting 1519 from 1582 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
217 goes into 630 2 times with a remainder of 196.
Use 2 as the next digit of our solution. 
Result so far: 399177.2
If we subtract 434 from 630, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 10:
The number 217 fits into 1960 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 399177.29
The remainder is 7 after subtracting 1953 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
The number 217 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 399177.29
Subtracting 0 from 70 leaves us 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.

On to step 12:
217 can be fit into 700 3 times, resulting in a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 399177.2903
If we take 651 away from 700, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 13:
If we divide 490 by 217, we get 2 and a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 399177.29032
If we subtract 434 from 490, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
217 can be fit into 560 2 times, resulting in a remainder of 126.
The number 2 becomes the next digit in our result. 
Result so far: 399177.290322
Deduct 434 from 560 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Our division results in 399177.290322 with a remaining 1.26e-05.
