56478885 ÷ 670 
Our goal is to divide 56478885 by 670.

Step 1:
If we divide 5 by 670, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 670

Step 2:
When dividing 56 by 670, we get 0 with a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 670

Moving on to step 3:
The number 670 fits into 564 0 times, leaving a remainder of 564.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 564, we get 564.
Grab the next digit (7) from the dividend, add it to 564, then carry on: 5647 / 670

Moving on to step 4:
If we divide 5647 by 670, we get 8 and a remainder of 287.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 5360 away from 5647, we end up with 287.
Append the next digit (8) from the dividend to 287 and continue with: 2878 / 670

Going ahead to step 5:
670 can be fit into 2878 4 times, resulting in a remainder of 198.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtract 2680 from 2878 to get 198.
Include the next digit (8) from the dividend after 198, then repeat: 1988 / 670

Step 6:
The number 670 fits into 1988 2 times, leaving a remainder of 648.
Record the quotient 2 as the next digit in the result. 
Result so far: 842.0
If we subtract 1340 from 1988, we get 648.
Grab the next digit (8) from the dividend, add it to 648, then carry on: 6488 / 670

Moving on to step 7:
670 can be fit into 6488 9 times, resulting in a remainder of 458.
Record the quotient 9 as the next digit in the result. 
Result so far: 8429.0
Subtracting 6030 from 6488 leaves us with 458.
Include the next digit (5) from the dividend after 458, then repeat: 4585 / 670

On to step 8:
4585 divided by 670 is 6 with a remainder of 565.
Put 6 as the next digit of the answer. 
Result so far: 84296.0
Deduct 4020 from 4585 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Let's proceed to step 9:
670 can be fit into 5650 8 times, resulting in a remainder of 290.
The next digit of our result is 8. 
Result so far: 84296.8
Subtracting 5360 from 5650 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 10:
When dividing 2900 by 670, we get 4 with a remainder of 220.
The number 4 becomes the next digit in our result. 
Result so far: 84296.84
If we subtract 2680 from 2900, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
The number 670 fits into 2200 3 times, leaving a remainder of 190.
The next digit of our result is 3. 
Result so far: 84296.843
Deduct 2010 from 2200 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 12:
1900 divided by 670 is 2 with a remainder of 560.
Use 2 as the next digit of our solution. 
Result so far: 84296.8432
Deduct 1340 from 1900 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 13:
670 can be fit into 5600 8 times, resulting in a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 84296.84328
Deduct 5360 from 5600 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 14:
When dividing 2400 by 670, we get 3 with a remainder of 390.
Use 3 as the next digit of our solution. 
Result so far: 84296.843283
Subtract 2010 from 2400 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 15:
3900 divided by 670 is 5 with a remainder of 550.
Put 5 as the next digit of the answer. 
Result so far: 84296.8432835
Subtract 3350 from 3900 to 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.

Step 16:
If we divide 5500 by 670, we get 8 and a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 84296.84328358
The remainder is 140 after subtracting 5360 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 84296.84328358 and a remainder of 1.4e-07.
