79898351 divided by 173 
Our goal is to divide 79898351 by 173.

Step 1:
The number 173 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 173

Moving on to step 2:
79 divided by 173 is 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 173

Step 3:
173 can be fit into 798 4 times, resulting in a remainder of 106.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 692 from 798 to get 106.
Take the next digit (9) from the dividend and append it to 106, then repeat: 1069 / 173

Moving on to step 4:
1069 divided by 173 is 6 with a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Deduct 1038 from 1069 and we're left with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 173

Step 5:
318 divided by 173 is 1 with a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 461.0
Subtracting 173 from 318 leaves us with 145.
Grab the next digit (3) from the dividend, add it to 145, then carry on: 1453 / 173

On to step 6:
If we divide 1453 by 173, we get 8 and a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 4618.0
Subtract 1384 from 1453 to get 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 173

Going ahead to step 7:
695 divided by 173 is 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 46184.0
If we take 692 away from 695, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 173

Going ahead to step 8:
173 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 461840.0
Deduct 0 from 31 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
When dividing 310 by 173, we get 1 with a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 461840.1
If we take 173 away from 310, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 10:
The number 173 fits into 1370 7 times, leaving a remainder of 159.
Use 7 as the next digit of our solution. 
Result so far: 461840.17
The remainder is 159 after subtracting 1211 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 11:
173 goes into 1590 9 times with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 461840.179
Subtracting 1557 from 1590 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 12:
173 can be fit into 330 1 times, resulting in a remainder of 157.
The next digit of our result is 1. 
Result so far: 461840.1791
Deduct 173 from 330 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 13:
When dividing 1570 by 173, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 461840.17919
Subtract 1557 from 1570 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
When dividing 130 by 173, we get 0 with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 461840.17919
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 15:
The number 173 fits into 1300 7 times, leaving a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 461840.1791907
If we subtract 1211 from 1300, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 16:
If we divide 890 by 173, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 461840.17919075
If we subtract 865 from 890, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 461840.17919075 with a remainder of 2.5e-08.
