Let's divide 53478408 by 670
We want to figure out the number of times 53478408 can be divided by 670.

Going ahead to step 1:
5 divided by 670 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 670

Advancing to step 2:
670 can be fit into 53 0 times, resulting in a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 670

On to step 3:
670 goes into 534 0 times with a remainder of 534.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 534 after subtracting 0 from 534.
Take the next digit (7) from the dividend and append it to 534, then repeat: 5347 / 670

On to step 4:
If we divide 5347 by 670, we get 7 and a remainder of 657.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 4690 from 5347, we get 657.
Grab the next digit (8) from the dividend, add it to 657, then carry on: 6578 / 670

Going ahead to step 5:
670 goes into 6578 9 times with a remainder of 548.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtracting 6030 from 6578 leaves us with 548.
Grab the next digit (4) from the dividend, add it to 548, then carry on: 5484 / 670

Let's proceed to step 6:
670 goes into 5484 8 times with a remainder of 124.
Record the quotient 8 as the next digit in the result. 
Result so far: 798.0
Deduct 5360 from 5484 and we're left with 124.
Take the next digit (0) from the dividend and append it to 124, then repeat: 1240 / 670

On to step 7:
When dividing 1240 by 670, we get 1 with a remainder of 570.
Write down 1 as next digit of the result. 
Result so far: 7981.0
Deduct 670 from 1240 and we're left with 570.
Include the next digit (8) from the dividend after 570, then repeat: 5708 / 670

Let's proceed to step 8:
5708 divided by 670 is 8 with a remainder of 348.
The number 8 becomes the next digit in our result. 
Result so far: 79818.0
Subtract 5360 from 5708 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 9:
670 can be fit into 3480 5 times, resulting in a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 79818.5
If we take 3350 away from 3480, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
670 can be fit into 1300 1 times, resulting in a remainder of 630.
The number 1 becomes the next digit in our result. 
Result so far: 79818.51
If we subtract 670 from 1300, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 11:
If we divide 6300 by 670, we get 9 and a remainder of 270.
Use 9 as the next digit of our solution. 
Result so far: 79818.519
Deduct 6030 from 6300 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 12:
If we divide 2700 by 670, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 79818.5194
Subtracting 2680 from 2700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
If we divide 200 by 670, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 79818.5194
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
When dividing 2000 by 670, we get 2 with a remainder of 660.
The next digit of our result is 2. 
Result so far: 79818.519402
If we take 1340 away from 2000, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 15:
When dividing 6600 by 670, we get 9 with a remainder of 570.
The next digit of our result is 9. 
Result so far: 79818.5194029
Subtracting 6030 from 6600 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 16:
5700 divided by 670 is 8 with a remainder of 340.
Record the quotient 8 as the next digit in the result. 
Result so far: 79818.51940298
Deduct 5360 from 5700 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The quotient of the division is 79818.51940298, and the remainder is 3.4e-07.
