We look at the division of 53881741 by 669 
Let's see how many times 669 fits into 53881741.

On to step 1:
5 divided by 669 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 669

Step 2:
669 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 669

Going ahead to step 3:
538 divided by 669 is 0 with a remainder of 538.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 538 and we're left with 538.
Grab the next digit (8) from the dividend, add it to 538, then carry on: 5388 / 669

Advancing to step 4:
669 can be fit into 5388 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 5352 from 5388 and we're left with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 669

Step 5:
669 goes into 361 0 times with a remainder of 361.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we subtract 0 from 361, we get 361.
Take the next digit (7) from the dividend and append it to 361, then repeat: 3617 / 669

On to step 6:
669 goes into 3617 5 times with a remainder of 272.
Put 5 as the next digit of the answer. 
Result so far: 805.0
Deduct 3345 from 3617 and we're left with 272.
Grab the next digit (4) from the dividend, add it to 272, then carry on: 2724 / 669

Advancing to step 7:
When dividing 2724 by 669, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 8054.0
If we subtract 2676 from 2724, we get 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 669

Advancing to step 8:
481 divided by 669 is 0 with a remainder of 481.
Use 0 as the next digit of our solution. 
Result so far: 80540.0
If we take 0 away from 481, we end up with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Step 9:
669 can be fit into 4810 7 times, resulting in a remainder of 127.
Record the quotient 7 as the next digit in the result. 
Result so far: 80540.7
Deduct 4683 from 4810 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 10:
The number 669 fits into 1270 1 times, leaving a remainder of 601.
Put 1 as the next digit of the answer. 
Result so far: 80540.71
The remainder is 601 after subtracting 669 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Step 11:
669 goes into 6010 8 times with a remainder of 658.
The next digit of our result is 8. 
Result so far: 80540.718
If we subtract 5352 from 6010, we get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Going ahead to step 12:
6580 divided by 669 is 9 with a remainder of 559.
Write down 9 as next digit of the result. 
Result so far: 80540.7189
If we subtract 6021 from 6580, we get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Step 13:
669 goes into 5590 8 times with a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 80540.71898
Deduct 5352 from 5590 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 14:
When dividing 2380 by 669, we get 3 with a remainder of 373.
Record the quotient 3 as the next digit in the result. 
Result so far: 80540.718983
Subtract 2007 from 2380 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 15:
If we divide 3730 by 669, we get 5 and a remainder of 385.
Record the quotient 5 as the next digit in the result. 
Result so far: 80540.7189835
Subtract 3345 from 3730 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Let's proceed to step 16:
The number 669 fits into 3850 5 times, leaving a remainder of 505.
Record the quotient 5 as the next digit in the result. 
Result so far: 80540.71898355
If we take 3345 away from 3850, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

In conclusion, the division gives 80540.71898355 with a balance of 5.05e-07.
