Let's divide 421607 by 27
We want to divide 421607 by 27.

Advancing to step 1:
The number 27 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 27

Going ahead to step 2:
If we divide 42 by 27, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
If we take 27 away from 42, we end up with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 27

Advancing to step 3:
If we divide 151 by 27, we get 5 and a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 135 away from 151, we end up with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 27

Going ahead to step 4:
If we divide 166 by 27, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 156.0
Subtracting 162 from 166 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 27

Step 5:
When dividing 40 by 27, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1561.0
If we take 27 away from 40, we end up with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 27

Step 6:
27 can be fit into 137 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 15615.0
If we take 135 away from 137, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 27, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 15615.0
Subtract 0 from 20 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.

On to step 8:
The number 27 fits into 200 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 15615.07
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
27 goes into 110 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 15615.074
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
If we divide 20 by 27, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 15615.074
Subtracting 0 from 20 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.

Let's proceed to step 11:
When dividing 200 by 27, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 15615.07407
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
When dividing 110 by 27, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 15615.074074
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
27 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 15615.074074
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
27 goes into 200 7 times with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 15615.07407407
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 15615.07407407, with a leftover of 1.1e-08.
