Let's divide 51009429 by 628
Let's see how many times 628 fits into 51009429.

Going ahead to step 1:
When dividing 5 by 628, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 628

On to step 2:
When dividing 51 by 628, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 628

Advancing to step 3:
The number 628 fits into 510 0 times, leaving a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 510 to get 510.
Grab the next digit (0) from the dividend, add it to 510, then carry on: 5100 / 628

Let's proceed to step 4:
The number 628 fits into 5100 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 5024 from 5100 to get 76.
Fetch the next digit (9) from the dividend, attach it to 76 and continue: 769 / 628

Let's proceed to step 5:
If we divide 769 by 628, we get 1 and a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 81.0
Subtracting 628 from 769 leaves us with 141.
Grab the next digit (4) from the dividend, add it to 141, then carry on: 1414 / 628

On to step 6:
When dividing 1414 by 628, we get 2 with a remainder of 158.
Put 2 as the next digit of the answer. 
Result so far: 812.0
If we take 1256 away from 1414, we end up with 158.
Take the next digit (2) from the dividend and append it to 158, then repeat: 1582 / 628

Moving on to step 7:
1582 divided by 628 is 2 with a remainder of 326.
Record the quotient 2 as the next digit in the result. 
Result so far: 8122.0
Subtract 1256 from 1582 to get 326.
Grab the next digit (9) from the dividend, add it to 326, then carry on: 3269 / 628

Moving on to step 8:
628 goes into 3269 5 times with a remainder of 129.
Use 5 as the next digit of our solution. 
Result so far: 81225.0
Deduct 3140 from 3269 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 9:
628 can be fit into 1290 2 times, resulting in a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 81225.2
Subtracting 1256 from 1290 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
If we divide 340 by 628, we get 0 and a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 81225.2
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
If we divide 3400 by 628, we get 5 and a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 81225.205
If we subtract 3140 from 3400, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 12:
628 can be fit into 2600 4 times, resulting in a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 81225.2054
The remainder is 88 after subtracting 2512 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 13:
The number 628 fits into 880 1 times, leaving a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 81225.20541
Subtracting 628 from 880 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 14:
2520 divided by 628 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 81225.205414
If we subtract 2512 from 2520, we 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.

Going ahead to step 15:
The number 628 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 81225.205414
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
628 goes into 800 1 times with a remainder of 172.
Use 1 as the next digit of our solution. 
Result so far: 81225.20541401
Subtracting 628 from 800 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Our division results in 81225.20541401 with a remaining 1.72e-07.
