We look at the division of 25355568 by 173 
We want to figure out the number of times 25355568 can be divided by 173.

Step 1:
The number 173 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 173

Step 2:
173 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 173

Going ahead to step 3:
173 goes into 253 1 times with a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 173 from 253 and we're left with 80.
Grab the next digit (5) from the dividend, add it to 80, then carry on: 805 / 173

On to step 4:
When dividing 805 by 173, we get 4 with a remainder of 113.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 113 after subtracting 692 from 805.
Take the next digit (5) from the dividend and append it to 113, then repeat: 1135 / 173

Moving on to step 5:
1135 divided by 173 is 6 with a remainder of 97.
Put 6 as the next digit of the answer. 
Result so far: 146.0
The remainder is 97 after subtracting 1038 from 1135.
Take the next digit (5) from the dividend and append it to 97, then repeat: 975 / 173

On to step 6:
173 can be fit into 975 5 times, resulting in a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 1465.0
The remainder is 110 after subtracting 865 from 975.
Grab the next digit (6) from the dividend, add it to 110, then carry on: 1106 / 173

Advancing to step 7:
1106 divided by 173 is 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 14656.0
Subtracting 1038 from 1106 leaves us with 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 173

Step 8:
The number 173 fits into 688 3 times, leaving a remainder of 169.
Put 3 as the next digit of the answer. 
Result so far: 146563.0
Deduct 519 from 688 and we're left with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

On to step 9:
173 can be fit into 1690 9 times, resulting in a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 146563.9
If we take 1557 away from 1690, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 10:
When dividing 1330 by 173, we get 7 with a remainder of 119.
The next digit of our result is 7. 
Result so far: 146563.97
Subtract 1211 from 1330 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 11:
173 goes into 1190 6 times with a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 146563.976
Subtract 1038 from 1190 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 12:
If we divide 1520 by 173, we get 8 and a remainder of 136.
The next digit of our result is 8. 
Result so far: 146563.9768
Subtracting 1384 from 1520 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 13:
1360 divided by 173 is 7 with a remainder of 149.
Use 7 as the next digit of our solution. 
Result so far: 146563.97687
Subtracting 1211 from 1360 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 14:
If we divide 1490 by 173, we get 8 and a remainder of 106.
The next digit of our result is 8. 
Result so far: 146563.976878
If we subtract 1384 from 1490, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 15:
173 can be fit into 1060 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 146563.9768786
Subtracting 1038 from 1060 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 16:
173 can be fit into 220 1 times, resulting in a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 146563.97687861
Subtracting 173 from 220 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

In conclusion, the division gives 146563.97687861 with a balance of 4.7e-08.
