We're dividing 53866639 by 70 
We want to divide 53866639 by 70.

Let's proceed to step 1:
The number 70 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 70

On to step 2:
The number 70 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 70

Advancing to step 3:
If we divide 538 by 70, we get 7 and a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 48 after subtracting 490 from 538.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 70

Moving on to step 4:
70 goes into 486 6 times with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
The remainder is 66 after subtracting 420 from 486.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 70

Going ahead to step 5:
The number 70 fits into 666 9 times, leaving a remainder of 36.
The next digit of our result is 9. 
Result so far: 769.0
If we take 630 away from 666, we end up with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 70

Let's proceed to step 6:
70 can be fit into 366 5 times, resulting in a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 7695.0
Subtract 350 from 366 to get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 70

On to step 7:
163 divided by 70 is 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 76952.0
Subtracting 140 from 163 leaves us with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 70

Moving on to step 8:
The number 70 fits into 239 3 times, leaving a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 769523.0
If we take 210 away from 239, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
The number 70 fits into 290 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 769523.4
The remainder is 10 after subtracting 280 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
70 goes into 100 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 769523.41
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
300 divided by 70 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 769523.414
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
If we divide 200 by 70, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 769523.4142
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
70 goes into 600 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 769523.41428
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 769523.414285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 15:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 769523.4142857
Subtracting 490 from 500 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 16:
If we divide 100 by 70, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 769523.41428571
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 769523.41428571, and the remainder is 3e-08.
