When dividing 420 by 907, we get 0 with a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 420, we get 420.
Grab the next digit (1) from the dividend, add it to 420, then carry on: 4201 / 907

Advancing to step 4:
907 goes into 4201 4 times with a remainder of 573.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 3628 from 4201, we get 573.
Bring next digit (8) of the dividend behind the 573 and repeat the process: 5738 / 907

Moving on to step 5:
When dividing 5738 by 907, we get 6 with a remainder of 296.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Deduct 5442 from 5738 and we're left with 296.
Fetch the next digit (6) from the dividend, attach it to 296 and continue: 2966 / 907

Going ahead to step 6:
When dividing 2966 by 907, we get 3 with a remainder of 245.
Write down 3 as next digit of the result. 
Result so far: 463.0
Subtract 2721 from 2966 to get 245.
Bring next digit (7) of the dividend behind the 245 and repeat the process: 2457 / 907

Advancing to step 7:
907 can be fit into 2457 2 times, resulting in a remainder of 643.
Write down 2 as next digit of the result. 
Result so far: 4632.0
Subtract 1814 from 2457 to get 643.
Grab the next digit (1) from the dividend, add it to 643, then carry on: 6431 / 907

Moving on to step 8:
6431 divided by 907 is 7 with a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 46327.0
Subtract 6349 from 6431 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 9:
907 can be fit into 820 0 times, resulting in a remainder of 820.
Put 0 as the next digit of the answer. 
Result so far: 46327.0
Subtract 0 from 820 to get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 10:
When dividing 8200 by 907, we get 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 46327.09
If we subtract 8163 from 8200, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
If we divide 370 by 907, we get 0 and a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 46327.09
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 12:
907 goes into 3700 4 times with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 46327.0904
Subtract 3628 from 3700 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
907 goes into 720 0 times with a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 46327.0904
Subtract 0 from 720 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 14:
If we divide 7200 by 907, we get 7 and a remainder of 851.
Put 7 as the next digit of the answer. 
Result so far: 46327.090407
The remainder is 851 after subtracting 6349 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

On to step 15:
The number 907 fits into 8510 9 times, leaving a remainder of 347.
Record the quotient 9 as the next digit in the result. 
Result so far: 46327.0904079
The remainder is 347 after subtracting 8163 from 8510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Advancing to step 16:
If we divide 3470 by 907, we get 3 and a remainder of 749.
Record the quotient 3 as the next digit in the result. 
Result so far: 46327.09040793
If we take 2721 away from 3470, we end up with 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

Our division results in 46327.09040793 with a remaining 7.49e-07.
