Let's divide 51605061 by 669
Our goal is to divide 51605061 by 669.

On to step 1:
669 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 669

Let's proceed to step 2:
If we divide 51 by 669, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 669

Moving on to step 3:
When dividing 516 by 669, we get 0 with a remainder of 516.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 516 after subtracting 0 from 516.
Fetch the next digit (0) from the dividend, attach it to 516 and continue: 5160 / 669

On to step 4:
669 can be fit into 5160 7 times, resulting in a remainder of 477.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 4683 from 5160, we get 477.
Take the next digit (5) from the dividend and append it to 477, then repeat: 4775 / 669

On to step 5:
4775 divided by 669 is 7 with a remainder of 92.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtract 4683 from 4775 to get 92.
Bring next digit (0) of the dividend behind the 92 and repeat the process: 920 / 669

On to step 6:
920 divided by 669 is 1 with a remainder of 251.
The next digit of our result is 1. 
Result so far: 771.0
The remainder is 251 after subtracting 669 from 920.
Include the next digit (6) from the dividend after 251, then repeat: 2516 / 669

Going ahead to step 7:
If we divide 2516 by 669, we get 3 and a remainder of 509.
Put 3 as the next digit of the answer. 
Result so far: 7713.0
Subtract 2007 from 2516 to get 509.
Include the next digit (1) from the dividend after 509, then repeat: 5091 / 669

Advancing to step 8:
When dividing 5091 by 669, we get 7 with a remainder of 408.
The number 7 becomes the next digit in our result. 
Result so far: 77137.0
The remainder is 408 after subtracting 4683 from 5091.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 9:
669 can be fit into 4080 6 times, resulting in a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 77137.6
Subtracting 4014 from 4080 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
669 goes into 660 0 times with a remainder of 660.
The next digit of our result is 0. 
Result so far: 77137.6
The remainder is 660 after subtracting 0 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 11:
If we divide 6600 by 669, we get 9 and a remainder of 579.
Write down 9 as next digit of the result. 
Result so far: 77137.609
If we take 6021 away from 6600, we end up with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Going ahead to step 12:
If we divide 5790 by 669, we get 8 and a remainder of 438.
The next digit of our result is 8. 
Result so far: 77137.6098
Subtract 5352 from 5790 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 13:
669 can be fit into 4380 6 times, resulting in a remainder of 366.
Use 6 as the next digit of our solution. 
Result so far: 77137.60986
If we subtract 4014 from 4380, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 14:
669 goes into 3660 5 times with a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 77137.609865
Subtracting 3345 from 3660 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 15:
If we divide 3150 by 669, we get 4 and a remainder of 474.
The number 4 becomes the next digit in our result. 
Result so far: 77137.6098654
Deduct 2676 from 3150 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 16:
The number 669 fits into 4740 7 times, leaving a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 77137.60986547
Subtracting 4683 from 4740 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Our division results in 77137.60986547 with a remaining 5.7e-08.
