We're dividing 90187801 by 761 
We want to divide 90187801 by 761.

Step 1:
If we divide 9 by 761, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 761

Going ahead to step 2:
761 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (1) from the dividend and append it to 90, then repeat: 901 / 761

On to step 3:
When dividing 901 by 761, we get 1 with a remainder of 140.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 761 from 901 and we're left with 140.
Include the next digit (8) from the dividend after 140, then repeat: 1408 / 761

Going ahead to step 4:
1408 divided by 761 is 1 with a remainder of 647.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 761 from 1408 and we're left with 647.
Take the next digit (7) from the dividend and append it to 647, then repeat: 6477 / 761

Step 5:
761 goes into 6477 8 times with a remainder of 389.
Write down 8 as next digit of the result. 
Result so far: 118.0
Deduct 6088 from 6477 and we're left with 389.
Include the next digit (8) from the dividend after 389, then repeat: 3898 / 761

Going ahead to step 6:
761 can be fit into 3898 5 times, resulting in a remainder of 93.
Use 5 as the next digit of our solution. 
Result so far: 1185.0
Subtracting 3805 from 3898 leaves us with 93.
Bring next digit (0) of the dividend behind the 93 and repeat the process: 930 / 761

Going ahead to step 7:
761 goes into 930 1 times with a remainder of 169.
The next digit of our result is 1. 
Result so far: 11851.0
Deduct 761 from 930 and we're left with 169.
Grab the next digit (1) from the dividend, add it to 169, then carry on: 1691 / 761

Moving on to step 8:
761 goes into 1691 2 times with a remainder of 169.
The next digit of our result is 2. 
Result so far: 118512.0
Deduct 1522 from 1691 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:
The number 761 fits into 1690 2 times, leaving a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 118512.2
Subtract 1522 from 1690 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 10:
If we divide 1680 by 761, we get 2 and a remainder of 158.
The next digit of our result is 2. 
Result so far: 118512.22
Deduct 1522 from 1680 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The final outcome is 118512.22, with a leftover of 0.158.
