We look at the division of 42590829 by 217 
We want to figure out the number of times 42590829 can be divided by 217.

Let's proceed to step 1:
217 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 217

Step 2:
217 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 217

Going ahead to step 3:
The number 217 fits into 425 1 times, leaving a remainder of 208.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 217 away from 425, we end up with 208.
Grab the next digit (9) from the dividend, add it to 208, then carry on: 2089 / 217

Moving on to step 4:
217 goes into 2089 9 times with a remainder of 136.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 1953 away from 2089, we end up with 136.
Include the next digit (0) from the dividend after 136, then repeat: 1360 / 217

On to step 5:
If we divide 1360 by 217, we get 6 and a remainder of 58.
The next digit of our result is 6. 
Result so far: 196.0
Subtract 1302 from 1360 to get 58.
Append the next digit (8) from the dividend to 58 and continue with: 588 / 217

Moving on to step 6:
The number 217 fits into 588 2 times, leaving a remainder of 154.
Put 2 as the next digit of the answer. 
Result so far: 1962.0
The remainder is 154 after subtracting 434 from 588.
Bring next digit (2) of the dividend behind the 154 and repeat the process: 1542 / 217

On to step 7:
If we divide 1542 by 217, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 19627.0
If we subtract 1519 from 1542, we get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 217

Moving on to step 8:
217 can be fit into 239 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 196271.0
If we subtract 217 from 239, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
220 divided by 217 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 196271.1
Subtract 217 from 220 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
If we divide 30 by 217, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 196271.1
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 217 fits into 300 1 times, leaving a remainder of 83.
The next digit of our result is 1. 
Result so far: 196271.101
Deduct 217 from 300 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 12:
The number 217 fits into 830 3 times, leaving a remainder of 179.
Write down 3 as next digit of the result. 
Result so far: 196271.1013
Deduct 651 from 830 and we're left with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 13:
The number 217 fits into 1790 8 times, leaving a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 196271.10138
Deduct 1736 from 1790 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
540 divided by 217 is 2 with a remainder of 106.
Put 2 as the next digit of the answer. 
Result so far: 196271.101382
The remainder is 106 after subtracting 434 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 15:
217 goes into 1060 4 times with a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 196271.1013824
If we subtract 868 from 1060, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 16:
When dividing 1920 by 217, we get 8 with a remainder of 184.
The next digit of our result is 8. 
Result so far: 196271.10138248
Subtracting 1736 from 1920 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The quotient of the division is 196271.10138248, and the remainder is 1.84e-07.
