On to step 5:
If we divide 844 by 139, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 466.0
The remainder is 10 after subtracting 834 from 844.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 139

Moving on to step 6:
139 goes into 108 0 times with a remainder of 108.
Record the quotient 0 as the next digit in the result. 
Result so far: 4660.0
The remainder is 108 after subtracting 0 from 108.
Take the next digit (9) from the dividend and append it to 108, then repeat: 1089 / 139

Moving on to step 7:
If we divide 1089 by 139, we get 7 and a remainder of 116.
The next digit of our result is 7. 
Result so far: 46607.0
The remainder is 116 after subtracting 973 from 1089.
Bring next digit (1) of the dividend behind the 116 and repeat the process: 1161 / 139

On to step 8:
1161 divided by 139 is 8 with a remainder of 49.
The next digit of our result is 8. 
Result so far: 466078.0
Deduct 1112 from 1161 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
139 goes into 490 3 times with a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 466078.3
Subtracting 417 from 490 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 10:
139 can be fit into 730 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 466078.35
Deduct 695 from 730 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
The number 139 fits into 350 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 466078.352
Deduct 278 from 350 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
139 goes into 720 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 466078.3525
The remainder is 25 after subtracting 695 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 13:
When dividing 250 by 139, we get 1 with a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 466078.35251
Subtract 139 from 250 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 14:
If we divide 1110 by 139, we get 7 and a remainder of 137.
The number 7 becomes the next digit in our result. 
Result so far: 466078.352517
The remainder is 137 after subtracting 973 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 15:
If we divide 1370 by 139, we get 9 and a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 466078.3525179
Deduct 1251 from 1370 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 16:
1190 divided by 139 is 8 with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 466078.35251798
If we take 1112 away from 1190, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 466078.35251798 with a remaining 7.8e-08.
