We're dividing 51990889 by 74 
Let's see how many times 74 fits into 51990889.

Step 1:
When dividing 5 by 74, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
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 / 74

Let's proceed to step 2:
The number 74 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 74

Step 3:
74 goes into 519 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 518 from 519 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 74

On to step 4:
74 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 74

Advancing to step 5:
If we divide 190 by 74, we get 2 and a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 702.0
Deduct 148 from 190 and we're left with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 74

Moving on to step 6:
The number 74 fits into 428 5 times, leaving a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 7025.0
Subtract 370 from 428 to get 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 74

Moving on to step 7:
74 can be fit into 588 7 times, resulting in a remainder of 70.
The next digit of our result is 7. 
Result so far: 70257.0
Subtracting 518 from 588 leaves us with 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 74

On to step 8:
The number 74 fits into 709 9 times, leaving a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 702579.0
Subtracting 666 from 709 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
74 goes into 430 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 702579.5
Subtract 370 from 430 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
When dividing 600 by 74, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 702579.58
Subtract 592 from 600 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
If we divide 80 by 74, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 702579.581
Subtract 74 from 80 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
If we divide 60 by 74, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 702579.581
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
74 can be fit into 600 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 702579.58108
The remainder is 8 after subtracting 592 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
80 divided by 74 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 702579.581081
If we subtract 74 from 80, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 15:
If we divide 60 by 74, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 702579.581081
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
The number 74 fits into 600 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 702579.58108108
Subtract 592 from 600 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 702579.58108108 with a remainder of 8e-09.
