We're dividing 51128154 by 722 
We're looking to find how many times 722 goes into 51128154.

Let's proceed to step 1:
722 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 722

Advancing to step 2:
722 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 722

Let's proceed to step 3:
The number 722 fits into 511 0 times, leaving a remainder of 511.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 511, we get 511.
Grab the next digit (2) from the dividend, add it to 511, then carry on: 5112 / 722

Advancing to step 4:
722 can be fit into 5112 7 times, resulting in a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 5054 from 5112, we get 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 722

Step 5:
If we divide 588 by 722, we get 0 and a remainder of 588.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Deduct 0 from 588 and we're left with 588.
Include the next digit (1) from the dividend after 588, then repeat: 5881 / 722

Let's proceed to step 6:
5881 divided by 722 is 8 with a remainder of 105.
Record the quotient 8 as the next digit in the result. 
Result so far: 708.0
The remainder is 105 after subtracting 5776 from 5881.
Include the next digit (5) from the dividend after 105, then repeat: 1055 / 722

Advancing to step 7:
722 goes into 1055 1 times with a remainder of 333.
Use 1 as the next digit of our solution. 
Result so far: 7081.0
Subtracting 722 from 1055 leaves us with 333.
Include the next digit (4) from the dividend after 333, then repeat: 3334 / 722

Moving on to step 8:
722 can be fit into 3334 4 times, resulting in a remainder of 446.
The number 4 becomes the next digit in our result. 
Result so far: 70814.0
If we take 2888 away from 3334, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 9:
722 goes into 4460 6 times with a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 70814.6
Subtracting 4332 from 4460 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 10:
When dividing 1280 by 722, we get 1 with a remainder of 558.
Use 1 as the next digit of our solution. 
Result so far: 70814.61
Subtract 722 from 1280 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Advancing to step 11:
If we divide 5580 by 722, we get 7 and a remainder of 526.
The number 7 becomes the next digit in our result. 
Result so far: 70814.617
Deduct 5054 from 5580 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 12:
If we divide 5260 by 722, we get 7 and a remainder of 206.
Use 7 as the next digit of our solution. 
Result so far: 70814.6177
If we subtract 5054 from 5260, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

The final outcome is 70814.6177, with a leftover of 0.00206.
