Let's divide 54310151 by 669
We're looking to find how many times 669 goes into 54310151.

Going ahead to step 1:
When dividing 5 by 669, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 669

Moving on to step 2:
54 divided by 669 is 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 669

Moving on to step 3:
When dividing 543 by 669, we get 0 with a remainder of 543.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 543 to get 543.
Include the next digit (1) from the dividend after 543, then repeat: 5431 / 669

Advancing to step 4:
669 can be fit into 5431 8 times, resulting in a remainder of 79.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 5352 from 5431 and we're left with 79.
Take the next digit (0) from the dividend and append it to 79, then repeat: 790 / 669

Advancing to step 5:
The number 669 fits into 790 1 times, leaving a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtracting 669 from 790 leaves us with 121.
Append the next digit (1) from the dividend to 121 and continue with: 1211 / 669

On to step 6:
669 can be fit into 1211 1 times, resulting in a remainder of 542.
Put 1 as the next digit of the answer. 
Result so far: 811.0
Deduct 669 from 1211 and we're left with 542.
Take the next digit (5) from the dividend and append it to 542, then repeat: 5425 / 669

Let's proceed to step 7:
When dividing 5425 by 669, we get 8 with a remainder of 73.
Write down 8 as next digit of the result. 
Result so far: 8118.0
Subtract 5352 from 5425 to get 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 669

Going ahead to step 8:
If we divide 731 by 669, we get 1 and a remainder of 62.
The next digit of our result is 1. 
Result so far: 81181.0
Subtracting 669 from 731 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
The number 669 fits into 620 0 times, leaving a remainder of 620.
Record the quotient 0 as the next digit in the result. 
Result so far: 81181.0
If we take 0 away from 620, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 10:
The number 669 fits into 6200 9 times, leaving a remainder of 179.
Use 9 as the next digit of our solution. 
Result so far: 81181.09
Deduct 6021 from 6200 and we're left with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 11:
If we divide 1790 by 669, we get 2 and a remainder of 452.
Write down 2 as next digit of the result. 
Result so far: 81181.092
Subtracting 1338 from 1790 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 12:
4520 divided by 669 is 6 with a remainder of 506.
Put 6 as the next digit of the answer. 
Result so far: 81181.0926
If we subtract 4014 from 4520, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 13:
If we divide 5060 by 669, we get 7 and a remainder of 377.
The number 7 becomes the next digit in our result. 
Result so far: 81181.09267
The remainder is 377 after subtracting 4683 from 5060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 14:
669 goes into 3770 5 times with a remainder of 425.
The next digit of our result is 5. 
Result so far: 81181.092675
Deduct 3345 from 3770 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 15:
669 goes into 4250 6 times with a remainder of 236.
Use 6 as the next digit of our solution. 
Result so far: 81181.0926756
Deduct 4014 from 4250 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 16:
669 goes into 2360 3 times with a remainder of 353.
Write down 3 as next digit of the result. 
Result so far: 81181.09267563
Deduct 2007 from 2360 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Our division results in 81181.09267563 with a remaining 3.53e-07.
