72387984 ÷ 173 
We want to divide 72387984 by 173.

Going ahead to step 1:
7 divided by 173 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 173

Moving on to step 2:
173 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 173

Moving on to step 3:
173 goes into 723 4 times with a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 692 away from 723, we end up with 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 173

Moving on to step 4:
173 goes into 318 1 times with a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 173 from 318 leaves us with 145.
Bring next digit (7) of the dividend behind the 145 and repeat the process: 1457 / 173

Let's proceed to step 5:
The number 173 fits into 1457 8 times, leaving a remainder of 73.
Use 8 as the next digit of our solution. 
Result so far: 418.0
Deduct 1384 from 1457 and we're left with 73.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 173

Advancing to step 6:
173 goes into 739 4 times with a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 4184.0
The remainder is 47 after subtracting 692 from 739.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 173

Let's proceed to step 7:
173 can be fit into 478 2 times, resulting in a remainder of 132.
Put 2 as the next digit of the answer. 
Result so far: 41842.0
Subtract 346 from 478 to get 132.
Bring next digit (4) of the dividend behind the 132 and repeat the process: 1324 / 173

Advancing to step 8:
The number 173 fits into 1324 7 times, leaving a remainder of 113.
Put 7 as the next digit of the answer. 
Result so far: 418427.0
Deduct 1211 from 1324 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 9:
The number 173 fits into 1130 6 times, leaving a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 418427.6
If we take 1038 away from 1130, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
If we divide 920 by 173, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 418427.65
If we subtract 865 from 920, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
When dividing 550 by 173, we get 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 418427.653
Deduct 519 from 550 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 12:
If we divide 310 by 173, we get 1 and a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 418427.6531
Subtract 173 from 310 to get 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 13:
173 goes into 1370 7 times with a remainder of 159.
Put 7 as the next digit of the answer. 
Result so far: 418427.65317
If we subtract 1211 from 1370, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 14:
173 can be fit into 1590 9 times, resulting in a remainder of 33.
The next digit of our result is 9. 
Result so far: 418427.653179
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.

Step 15:
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: 418427.6531791
If we take 173 away from 330, we end up 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 16:
If we divide 1570 by 173, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 418427.65317919
If we subtract 1557 from 1570, we 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.

The quotient of the division is 418427.65317919, and the remainder is 1.3e-08.
