Let's divide 77653621 by 661
Our goal is to divide 77653621 by 661.

On to step 1:
661 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 661

Moving on to step 2:
77 divided by 661 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 661

On to step 3:
If we divide 776 by 661, we get 1 and a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 115 after subtracting 661 from 776.
Fetch the next digit (5) from the dividend, attach it to 115 and continue: 1155 / 661

Advancing to step 4:
When dividing 1155 by 661, we get 1 with a remainder of 494.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 661 from 1155, we get 494.
Take the next digit (3) from the dividend and append it to 494, then repeat: 4943 / 661

Going ahead to step 5:
4943 divided by 661 is 7 with a remainder of 316.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
Deduct 4627 from 4943 and we're left with 316.
Bring next digit (6) of the dividend behind the 316 and repeat the process: 3166 / 661

Going ahead to step 6:
661 can be fit into 3166 4 times, resulting in a remainder of 522.
Write down 4 as next digit of the result. 
Result so far: 1174.0
Deduct 2644 from 3166 and we're left with 522.
Grab the next digit (2) from the dividend, add it to 522, then carry on: 5222 / 661

Let's proceed to step 7:
661 goes into 5222 7 times with a remainder of 595.
The number 7 becomes the next digit in our result. 
Result so far: 11747.0
If we take 4627 away from 5222, we end up with 595.
Bring next digit (1) of the dividend behind the 595 and repeat the process: 5951 / 661

Moving on to step 8:
If we divide 5951 by 661, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 117479.0
Subtracting 5949 from 5951 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
661 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 117479.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
661 goes into 200 0 times with a remainder of 200.
The next digit of our result is 0. 
Result so far: 117479.0
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 117479.0 with a balance of 0.2.
