We're dividing 64094213 by 645 
Let's see how many times 645 fits into 64094213.

Going ahead to step 1:
645 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 645

Going ahead to step 2:
64 divided by 645 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 645

Moving on to step 3:
When dividing 640 by 645, we get 0 with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 640 leaves us with 640.
Append the next digit (9) from the dividend to 640 and continue with: 6409 / 645

On to step 4:
If we divide 6409 by 645, we get 9 and a remainder of 604.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 5805 from 6409 to get 604.
Include the next digit (4) from the dividend after 604, then repeat: 6044 / 645

Going ahead to step 5:
The number 645 fits into 6044 9 times, leaving a remainder of 239.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 5805 from 6044 to get 239.
Take the next digit (2) from the dividend and append it to 239, then repeat: 2392 / 645

Let's proceed to step 6:
645 goes into 2392 3 times with a remainder of 457.
Record the quotient 3 as the next digit in the result. 
Result so far: 993.0
If we subtract 1935 from 2392, we get 457.
Bring next digit (1) of the dividend behind the 457 and repeat the process: 4571 / 645

On to step 7:
645 can be fit into 4571 7 times, resulting in a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 9937.0
If we subtract 4515 from 4571, we get 56.
Grab the next digit (3) from the dividend, add it to 56, then carry on: 563 / 645

Step 8:
645 can be fit into 563 0 times, resulting in a remainder of 563.
Write down 0 as next digit of the result. 
Result so far: 99370.0
Subtract 0 from 563 to get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Step 9:
645 can be fit into 5630 8 times, resulting in a remainder of 470.
Record the quotient 8 as the next digit in the result. 
Result so far: 99370.8
The remainder is 470 after subtracting 5160 from 5630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 10:
If we divide 4700 by 645, we get 7 and a remainder of 185.
Put 7 as the next digit of the answer. 
Result so far: 99370.87
Subtract 4515 from 4700 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 11:
If we divide 1850 by 645, we get 2 and a remainder of 560.
Put 2 as the next digit of the answer. 
Result so far: 99370.872
If we subtract 1290 from 1850, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 12:
When dividing 5600 by 645, we get 8 with a remainder of 440.
Put 8 as the next digit of the answer. 
Result so far: 99370.8728
Subtracting 5160 from 5600 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 13:
When dividing 4400 by 645, we get 6 with a remainder of 530.
The next digit of our result is 6. 
Result so far: 99370.87286
Subtracting 3870 from 4400 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 14:
When dividing 5300 by 645, we get 8 with a remainder of 140.
Put 8 as the next digit of the answer. 
Result so far: 99370.872868
If we subtract 5160 from 5300, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
645 can be fit into 1400 2 times, resulting in a remainder of 110.
The next digit of our result is 2. 
Result so far: 99370.8728682
Deduct 1290 from 1400 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 16:
The number 645 fits into 1100 1 times, leaving a remainder of 455.
Record the quotient 1 as the next digit in the result. 
Result so far: 99370.87286821
If we take 645 away from 1100, we end up with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

The final outcome is 99370.87286821, with a leftover of 4.55e-07.
