We look at the division of 34640738 by 645 
We want to divide 34640738 by 645.

On to step 1:
The number 645 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 645

Step 2:
When dividing 34 by 645, we get 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 645

Going ahead to step 3:
645 goes into 346 0 times with a remainder of 346.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 346, we end up with 346.
Append the next digit (4) from the dividend to 346 and continue with: 3464 / 645

Moving on to step 4:
645 can be fit into 3464 5 times, resulting in a remainder of 239.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 3225 from 3464 leaves us with 239.
Grab the next digit (0) from the dividend, add it to 239, then carry on: 2390 / 645

On to step 5:
If we divide 2390 by 645, we get 3 and a remainder of 455.
The next digit of our result is 3. 
Result so far: 53.0
If we subtract 1935 from 2390, we get 455.
Take the next digit (7) from the dividend and append it to 455, then repeat: 4557 / 645

Let's proceed to step 6:
4557 divided by 645 is 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 537.0
The remainder is 42 after subtracting 4515 from 4557.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 645

On to step 7:
645 can be fit into 423 0 times, resulting in a remainder of 423.
The number 0 becomes the next digit in our result. 
Result so far: 5370.0
Subtract 0 from 423 to get 423.
Grab the next digit (8) from the dividend, add it to 423, then carry on: 4238 / 645

Going ahead to step 8:
645 goes into 4238 6 times with a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 53706.0
If we take 3870 away from 4238, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 9:
If we divide 3680 by 645, we get 5 and a remainder of 455.
Put 5 as the next digit of the answer. 
Result so far: 53706.5
Subtract 3225 from 3680 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 10:
4550 divided by 645 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 53706.57
Subtract 4515 from 4550 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
The number 645 fits into 350 0 times, leaving a remainder of 350.
The next digit of our result is 0. 
Result so far: 53706.57
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 12:
When dividing 3500 by 645, we get 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 53706.5705
If we take 3225 away from 3500, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 13:
2750 divided by 645 is 4 with a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 53706.57054
Subtract 2580 from 2750 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 14:
When dividing 1700 by 645, we get 2 with a remainder of 410.
Use 2 as the next digit of our solution. 
Result so far: 53706.570542
If we subtract 1290 from 1700, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 15:
If we divide 4100 by 645, we get 6 and a remainder of 230.
Record the quotient 6 as the next digit in the result. 
Result so far: 53706.5705426
The remainder is 230 after subtracting 3870 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 16:
645 goes into 2300 3 times with a remainder of 365.
Put 3 as the next digit of the answer. 
Result so far: 53706.57054263
Subtract 1935 from 2300 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

After the division, we end up with 53706.57054263 and a remainder of 3.65e-07.
