We divide 42458637 by 173
Our goal is to divide 42458637 by 173.

On to step 1:
If we divide 4 by 173, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 173

Advancing to step 2:
The number 173 fits into 42 0 times, leaving 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.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 173

Let's proceed to step 3:
The number 173 fits into 424 2 times, leaving a remainder of 78.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 346 from 424 to get 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 173

On to step 4:
If we divide 785 by 173, we get 4 and a remainder of 93.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 692 from 785 leaves us with 93.
Append the next digit (8) from the dividend to 93 and continue with: 938 / 173

Advancing to step 5:
If we divide 938 by 173, we get 5 and a remainder of 73.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
Subtracting 865 from 938 leaves us with 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 173

On to step 6:
173 can be fit into 736 4 times, resulting in a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 2454.0
If we take 692 away from 736, we end up with 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 173

Going ahead to step 7:
When dividing 443 by 173, we get 2 with a remainder of 97.
Put 2 as the next digit of the answer. 
Result so far: 24542.0
The remainder is 97 after subtracting 346 from 443.
Grab the next digit (7) from the dividend, add it to 97, then carry on: 977 / 173

Advancing to step 8:
The number 173 fits into 977 5 times, leaving a remainder of 112.
Write down 5 as next digit of the result. 
Result so far: 245425.0
If we subtract 865 from 977, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 9:
The number 173 fits into 1120 6 times, leaving a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 245425.6
The remainder is 82 after subtracting 1038 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
173 goes into 820 4 times with a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 245425.64
If we take 692 away from 820, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 11:
If we divide 1280 by 173, we get 7 and a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 245425.647
The remainder is 69 after subtracting 1211 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 12:
173 goes into 690 3 times with a remainder of 171.
Record the quotient 3 as the next digit in the result. 
Result so far: 245425.6473
The remainder is 171 after subtracting 519 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 13:
When dividing 1710 by 173, we get 9 with a remainder of 153.
Record the quotient 9 as the next digit in the result. 
Result so far: 245425.64739
Deduct 1557 from 1710 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 14:
173 can be fit into 1530 8 times, resulting in a remainder of 146.
Record the quotient 8 as the next digit in the result. 
Result so far: 245425.647398
Subtracting 1384 from 1530 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 15:
The number 173 fits into 1460 8 times, leaving a remainder of 76.
The next digit of our result is 8. 
Result so far: 245425.6473988
Subtracting 1384 from 1460 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 245425.6473988, with a leftover of 7.6e-07.
