46672078 divided by 645 
Let's see how many times 645 fits into 46672078.

Going ahead to step 1:
645 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 645

Step 2:
The number 645 fits into 46 0 times, leaving a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 645

Advancing to step 3:
The number 645 fits into 466 0 times, leaving a remainder of 466.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 466 to get 466.
Fetch the next digit (7) from the dividend, attach it to 466 and continue: 4667 / 645

Moving on to step 4:
4667 divided by 645 is 7 with a remainder of 152.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 152 after subtracting 4515 from 4667.
Include the next digit (2) from the dividend after 152, then repeat: 1522 / 645

On to step 5:
645 goes into 1522 2 times with a remainder of 232.
The next digit of our result is 2. 
Result so far: 72.0
Subtracting 1290 from 1522 leaves us with 232.
Grab the next digit (0) from the dividend, add it to 232, then carry on: 2320 / 645

On to step 6:
2320 divided by 645 is 3 with a remainder of 385.
Put 3 as the next digit of the answer. 
Result so far: 723.0
If we take 1935 away from 2320, we end up with 385.
Fetch the next digit (7) from the dividend, attach it to 385 and continue: 3857 / 645

Step 7:
645 goes into 3857 5 times with a remainder of 632.
Use 5 as the next digit of our solution. 
Result so far: 7235.0
Subtracting 3225 from 3857 leaves us with 632.
Include the next digit (8) from the dividend after 632, then repeat: 6328 / 645

Let's proceed to step 8:
When dividing 6328 by 645, we get 9 with a remainder of 523.
Write down 9 as next digit of the result. 
Result so far: 72359.0
If we take 5805 away from 6328, we end up with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

On to step 9:
645 goes into 5230 8 times with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 72359.8
Deduct 5160 from 5230 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
The number 645 fits into 700 1 times, leaving a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 72359.81
Deduct 645 from 700 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
When dividing 550 by 645, we get 0 with a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 72359.81
If we subtract 0 from 550, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 12:
If we divide 5500 by 645, we get 8 and a remainder of 340.
The next digit of our result is 8. 
Result so far: 72359.8108
Subtract 5160 from 5500 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 13:
645 can be fit into 3400 5 times, resulting in a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 72359.81085
If we take 3225 away from 3400, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 14:
645 can be fit into 1750 2 times, resulting in a remainder of 460.
Write down 2 as next digit of the result. 
Result so far: 72359.810852
If we take 1290 away from 1750, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 15:
645 can be fit into 4600 7 times, resulting in a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 72359.8108527
Subtract 4515 from 4600 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 16:
If we divide 850 by 645, we get 1 and a remainder of 205.
Put 1 as the next digit of the answer. 
Result so far: 72359.81085271
Subtracting 645 from 850 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final outcome is 72359.81085271, with a leftover of 2.05e-07.
