Let's divide 20690571 by 420
Let's see how many times 420 fits into 20690571.

On to step 1:
420 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 420

Advancing to step 2:
The number 420 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 420

Moving on to step 3:
206 divided by 420 is 0 with a remainder of 206.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 206 to get 206.
Bring next digit (9) of the dividend behind the 206 and repeat the process: 2069 / 420

Let's proceed to step 4:
If we divide 2069 by 420, we get 4 and a remainder of 389.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1680 from 2069 and we're left with 389.
Take the next digit (0) from the dividend and append it to 389, then repeat: 3890 / 420

Advancing to step 5:
The number 420 fits into 3890 9 times, leaving a remainder of 110.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtract 3780 from 3890 to get 110.
Bring next digit (5) of the dividend behind the 110 and repeat the process: 1105 / 420

Step 6:
If we divide 1105 by 420, we get 2 and a remainder of 265.
The next digit of our result is 2. 
Result so far: 492.0
If we take 840 away from 1105, we end up with 265.
Append the next digit (7) from the dividend to 265 and continue with: 2657 / 420

Step 7:
When dividing 2657 by 420, we get 6 with a remainder of 137.
Write down 6 as next digit of the result. 
Result so far: 4926.0
If we subtract 2520 from 2657, we get 137.
Grab the next digit (1) from the dividend, add it to 137, then carry on: 1371 / 420

Going ahead to step 8:
If we divide 1371 by 420, we get 3 and a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 49263.0
Subtracting 1260 from 1371 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 9:
When dividing 1110 by 420, we get 2 with a remainder of 270.
Use 2 as the next digit of our solution. 
Result so far: 49263.2
Subtracting 840 from 1110 leaves us 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.

Advancing to step 10:
2700 divided by 420 is 6 with a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 49263.26
Subtracting 2520 from 2700 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
If we divide 1800 by 420, we get 4 and a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 49263.264
Subtracting 1680 from 1800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
The number 420 fits into 1200 2 times, leaving a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 49263.2642
If we subtract 840 from 1200, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 13:
When dividing 3600 by 420, we get 8 with a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 49263.26428
If we take 3360 away from 3600, we end up 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.

Let's proceed to step 14:
The number 420 fits into 2400 5 times, leaving a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 49263.264285
Subtract 2100 from 2400 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 15:
The number 420 fits into 3000 7 times, leaving a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 49263.2642857
If we take 2940 away from 3000, we end up 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.

Moving on to step 16:
The number 420 fits into 600 1 times, leaving a remainder of 180.
Use 1 as the next digit of our solution. 
Result so far: 49263.26428571
Subtracting 420 from 600 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 49263.26428571, and the remainder is 1.8e-07.
