51351929 ÷ 738 
Let's see how many times 738 fits into 51351929.

On to step 1:
738 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 738

Step 2:
When dividing 51 by 738, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 738

Advancing to step 3:
738 can be fit into 513 0 times, resulting in a remainder of 513.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 513 to get 513.
Fetch the next digit (5) from the dividend, attach it to 513 and continue: 5135 / 738

Moving on to step 4:
5135 divided by 738 is 6 with a remainder of 707.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 707 after subtracting 4428 from 5135.
Fetch the next digit (1) from the dividend, attach it to 707 and continue: 7071 / 738

Advancing to step 5:
738 can be fit into 7071 9 times, resulting in a remainder of 429.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Deduct 6642 from 7071 and we're left with 429.
Grab the next digit (9) from the dividend, add it to 429, then carry on: 4299 / 738

Moving on to step 6:
738 goes into 4299 5 times with a remainder of 609.
Put 5 as the next digit of the answer. 
Result so far: 695.0
Subtract 3690 from 4299 to get 609.
Grab the next digit (2) from the dividend, add it to 609, then carry on: 6092 / 738

Going ahead to step 7:
If we divide 6092 by 738, we get 8 and a remainder of 188.
Record the quotient 8 as the next digit in the result. 
Result so far: 6958.0
Subtract 5904 from 6092 to get 188.
Include the next digit (9) from the dividend after 188, then repeat: 1889 / 738

Let's proceed to step 8:
When dividing 1889 by 738, we get 2 with a remainder of 413.
Write down 2 as next digit of the result. 
Result so far: 69582.0
Subtract 1476 from 1889 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Advancing to step 9:
The number 738 fits into 4130 5 times, leaving a remainder of 440.
Use 5 as the next digit of our solution. 
Result so far: 69582.5
Subtract 3690 from 4130 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 10:
The number 738 fits into 4400 5 times, leaving a remainder of 710.
The next digit of our result is 5. 
Result so far: 69582.55
Subtract 3690 from 4400 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Our division results in 69582.55 with a remaining 0.71.
