We look at the division of 644046 by 76 
We're looking to find how many times 76 goes into 644046.

Moving on to step 1:
When dividing 6 by 76, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 76

On to step 2:
76 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 76

Let's proceed to step 3:
76 goes into 644 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 608 from 644 and we're left with 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 76

Advancing to step 4:
If we divide 360 by 76, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 84.0
If we take 304 away from 360, we end up with 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 76

Let's proceed to step 5:
If we divide 564 by 76, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 847.0
Deduct 532 from 564 and we're left with 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 76

Let's proceed to step 6:
When dividing 326 by 76, we get 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 8474.0
Deduct 304 from 326 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
The number 76 fits into 220 2 times, leaving a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 8474.2
Subtracting 152 from 220 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
The number 76 fits into 680 8 times, leaving a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 8474.28
Deduct 608 from 680 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
When dividing 720 by 76, we get 9 with a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 8474.289
Subtract 684 from 720 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
76 can be fit into 360 4 times, resulting in a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 8474.2894
If we take 304 away from 360, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
76 goes into 560 7 times with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 8474.28947
Subtract 532 from 560 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
76 goes into 280 3 times with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 8474.289473
If we subtract 228 from 280, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
If we divide 520 by 76, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 8474.2894736
Deduct 456 from 520 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
The number 76 fits into 640 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8474.28947368
If we take 608 away from 640, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 8474.28947368 and a remainder of 3.2e-08.
