66961238 ÷ 173 
We want to divide 66961238 by 173.

Advancing to step 1:
The number 173 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 173

Going ahead to step 2:
The number 173 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 173

Let's proceed to step 3:
If we divide 669 by 173, we get 3 and a remainder of 150.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 519 from 669 and we're left with 150.
Fetch the next digit (6) from the dividend, attach it to 150 and continue: 1506 / 173

Advancing to step 4:
173 goes into 1506 8 times with a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 122 after subtracting 1384 from 1506.
Bring next digit (1) of the dividend behind the 122 and repeat the process: 1221 / 173

Let's proceed to step 5:
173 goes into 1221 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 387.0
Subtracting 1211 from 1221 leaves us with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 173

Advancing to step 6:
When dividing 102 by 173, we get 0 with a remainder of 102.
Put 0 as the next digit of the answer. 
Result so far: 3870.0
If we take 0 away from 102, we end up with 102.
Fetch the next digit (3) from the dividend, attach it to 102 and continue: 1023 / 173

Moving on to step 7:
The number 173 fits into 1023 5 times, leaving a remainder of 158.
The next digit of our result is 5. 
Result so far: 38705.0
If we take 865 away from 1023, we end up with 158.
Fetch the next digit (8) from the dividend, attach it to 158 and continue: 1588 / 173

On to step 8:
When dividing 1588 by 173, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 387059.0
If we subtract 1557 from 1588, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
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: 387059.1
The remainder is 137 after subtracting 173 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 10:
173 goes into 1370 7 times with a remainder of 159.
The next digit of our result is 7. 
Result so far: 387059.17
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.

Step 11:
1590 divided by 173 is 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 387059.179
Deduct 1557 from 1590 and we're left 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:
When dividing 330 by 173, we get 1 with a remainder of 157.
Use 1 as the next digit of our solution. 
Result so far: 387059.1791
The remainder is 157 after subtracting 173 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 13:
The number 173 fits into 1570 9 times, leaving a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 387059.17919
If we take 1557 away from 1570, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
When dividing 130 by 173, we get 0 with a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 387059.17919
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.

On to step 15:
173 can be fit into 1300 7 times, resulting in a remainder of 89.
Use 7 as the next digit of our solution. 
Result so far: 387059.1791907
If we take 1211 away from 1300, we end up with 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:
890 divided by 173 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 387059.17919075
Subtracting 865 from 890 leaves us with 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 387059.17919075 with a remainder of 2.5e-08.
