We look at the division of 51433437 by 660 
We want to figure out the number of times 51433437 can be divided by 660.

Advancing to step 1:
660 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 660

Step 2:
If we divide 51 by 660, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 660

Going ahead to step 3:
660 can be fit into 514 0 times, resulting in a remainder of 514.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 514 to get 514.
Bring next digit (3) of the dividend behind the 514 and repeat the process: 5143 / 660

Advancing to step 4:
660 goes into 5143 7 times with a remainder of 523.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 4620 from 5143 to get 523.
Bring next digit (3) of the dividend behind the 523 and repeat the process: 5233 / 660

Advancing to step 5:
660 goes into 5233 7 times with a remainder of 613.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we take 4620 away from 5233, we end up with 613.
Fetch the next digit (4) from the dividend, attach it to 613 and continue: 6134 / 660

Step 6:
When dividing 6134 by 660, we get 9 with a remainder of 194.
The number 9 becomes the next digit in our result. 
Result so far: 779.0
If we take 5940 away from 6134, we end up with 194.
Grab the next digit (3) from the dividend, add it to 194, then carry on: 1943 / 660

On to step 7:
If we divide 1943 by 660, we get 2 and a remainder of 623.
The number 2 becomes the next digit in our result. 
Result so far: 7792.0
Subtracting 1320 from 1943 leaves us with 623.
Bring next digit (7) of the dividend behind the 623 and repeat the process: 6237 / 660

Advancing to step 8:
660 goes into 6237 9 times with a remainder of 297.
The number 9 becomes the next digit in our result. 
Result so far: 77929.0
The remainder is 297 after subtracting 5940 from 6237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 9:
660 goes into 2970 4 times with a remainder of 330.
Use 4 as the next digit of our solution. 
Result so far: 77929.4
The remainder is 330 after subtracting 2640 from 2970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 10:
660 goes into 3300 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 77929.45
Deduct 3300 from 3300 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
660 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 77929.45
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
If we divide 0 by 660, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 77929.45
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 77929.45, and the remainder is 0.0.
