51914334 ÷ 4 
We're looking to find how many times 4 goes into 51914334.

Step 1:
If we divide 5 by 4, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 4 from 5.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 4

Moving on to step 2:
11 divided by 4 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 8 from 11 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 4

Going ahead to step 3:
When dividing 39 by 4, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtract 36 from 39 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 4

Let's proceed to step 4:
When dividing 31 by 4, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1297.0
If we take 28 away from 31, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 4

Step 5:
When dividing 34 by 4, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 12978.0
If we take 32 away from 34, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 4

On to step 6:
When dividing 23 by 4, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 129785.0
Subtracting 20 from 23 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 4

Moving on to step 7:
4 can be fit into 33 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1297858.0
The remainder is 1 after subtracting 32 from 33.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 4

Step 8:
If we divide 14 by 4, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 12978583.0
Subtract 12 from 14 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
20 divided by 4 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12978583.5
Subtracting 20 from 20 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 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12978583.5
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.

Step 11:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12978583.5
Deduct 0 from 0 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.

The final result is 12978583.5 with a remainder of 0.0.
