We're dividing 53531219 by 661 
We're looking to find how many times 661 goes into 53531219.

On to step 1:
The number 661 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 661

Advancing to step 2:
661 goes into 53 0 times with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 661

Moving on to step 3:
The number 661 fits into 535 0 times, leaving a remainder of 535.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 535 and we're left with 535.
Bring next digit (3) of the dividend behind the 535 and repeat the process: 5353 / 661

Step 4:
The number 661 fits into 5353 8 times, leaving a remainder of 65.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 5288 away from 5353, we end up with 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 661

Advancing to step 5:
The number 661 fits into 651 0 times, leaving a remainder of 651.
Put 0 as the next digit of the answer. 
Result so far: 80.0
The remainder is 651 after subtracting 0 from 651.
Bring next digit (2) of the dividend behind the 651 and repeat the process: 6512 / 661

Going ahead to step 6:
6512 divided by 661 is 9 with a remainder of 563.
Write down 9 as next digit of the result. 
Result so far: 809.0
If we take 5949 away from 6512, we end up with 563.
Grab the next digit (1) from the dividend, add it to 563, then carry on: 5631 / 661

Advancing to step 7:
The number 661 fits into 5631 8 times, leaving a remainder of 343.
Record the quotient 8 as the next digit in the result. 
Result so far: 8098.0
Subtracting 5288 from 5631 leaves us with 343.
Fetch the next digit (9) from the dividend, attach it to 343 and continue: 3439 / 661

Advancing to step 8:
3439 divided by 661 is 5 with a remainder of 134.
Record the quotient 5 as the next digit in the result. 
Result so far: 80985.0
Deduct 3305 from 3439 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 9:
If we divide 1340 by 661, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 80985.2
Deduct 1322 from 1340 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
The number 661 fits into 180 0 times, leaving a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 80985.2
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
If we divide 1800 by 661, we get 2 and a remainder of 478.
The number 2 becomes the next digit in our result. 
Result so far: 80985.202
If we subtract 1322 from 1800, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 12:
If we divide 4780 by 661, we get 7 and a remainder of 153.
Write down 7 as next digit of the result. 
Result so far: 80985.2027
The remainder is 153 after subtracting 4627 from 4780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 13:
1530 divided by 661 is 2 with a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 80985.20272
The remainder is 208 after subtracting 1322 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 14:
661 can be fit into 2080 3 times, resulting in a remainder of 97.
Use 3 as the next digit of our solution. 
Result so far: 80985.202723
If we subtract 1983 from 2080, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 15:
If we divide 970 by 661, we get 1 and a remainder of 309.
Put 1 as the next digit of the answer. 
Result so far: 80985.2027231
If we subtract 661 from 970, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 16:
661 can be fit into 3090 4 times, resulting in a remainder of 446.
The next digit of our result is 4. 
Result so far: 80985.20272314
The remainder is 446 after subtracting 2644 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

The final outcome is 80985.20272314, with a leftover of 4.46e-07.
