We divide 86937951 by 578
Our goal is to divide 86937951 by 578.

On to step 1:
When dividing 8 by 578, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 578

Step 2:
If we divide 86 by 578, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 578

Step 3:
869 divided by 578 is 1 with a remainder of 291.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 578 from 869 and we're left with 291.
Append the next digit (3) from the dividend to 291 and continue with: 2913 / 578

Going ahead to step 4:
The number 578 fits into 2913 5 times, leaving a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 2890 from 2913 to get 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 578

On to step 5:
237 divided by 578 is 0 with a remainder of 237.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
The remainder is 237 after subtracting 0 from 237.
Include the next digit (9) from the dividend after 237, then repeat: 2379 / 578

Advancing to step 6:
The number 578 fits into 2379 4 times, leaving a remainder of 67.
Use 4 as the next digit of our solution. 
Result so far: 1504.0
Subtract 2312 from 2379 to get 67.
Take the next digit (5) from the dividend and append it to 67, then repeat: 675 / 578

Step 7:
675 divided by 578 is 1 with a remainder of 97.
Write down 1 as next digit of the result. 
Result so far: 15041.0
Deduct 578 from 675 and we're left with 97.
Fetch the next digit (1) from the dividend, attach it to 97 and continue: 971 / 578

On to step 8:
578 can be fit into 971 1 times, resulting in a remainder of 393.
Write down 1 as next digit of the result. 
Result so far: 150411.0
The remainder is 393 after subtracting 578 from 971.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Going ahead to step 9:
578 goes into 3930 6 times with a remainder of 462.
The next digit of our result is 6. 
Result so far: 150411.6
If we take 3468 away from 3930, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 10:
578 goes into 4620 7 times with a remainder of 574.
The number 7 becomes the next digit in our result. 
Result so far: 150411.67
Deduct 4046 from 4620 and we're left with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Advancing to step 11:
578 goes into 5740 9 times with a remainder of 538.
The next digit of our result is 9. 
Result so far: 150411.679
Subtracting 5202 from 5740 leaves us with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Advancing to step 12:
When dividing 5380 by 578, we get 9 with a remainder of 178.
Record the quotient 9 as the next digit in the result. 
Result so far: 150411.6799
The remainder is 178 after subtracting 5202 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The final outcome is 150411.6799, with a leftover of 0.00178.
