Step 5:
217 divided by 122 is 1 with a remainder of 95.
The number 1 becomes the next digit in our result. 
Result so far: 421.0
Deduct 122 from 217 and we're left with 95.
Fetch the next digit (0) from the dividend, attach it to 95 and continue: 950 / 122

Going ahead to step 6:
When dividing 950 by 122, we get 7 with a remainder of 96.
The next digit of our result is 7. 
Result so far: 4217.0
Subtract 854 from 950 to get 96.
Append the next digit (7) from the dividend to 96 and continue with: 967 / 122

On to step 7:
967 divided by 122 is 7 with a remainder of 113.
The next digit of our result is 7. 
Result so far: 42177.0
If we subtract 854 from 967, we get 113.
Fetch the next digit (1) from the dividend, attach it to 113 and continue: 1131 / 122

Moving on to step 8:
If we divide 1131 by 122, we get 9 and a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 421779.0
If we subtract 1098 from 1131, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
When dividing 330 by 122, we get 2 with a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 421779.2
If we take 244 away from 330, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 10:
When dividing 860 by 122, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 421779.27
Subtract 854 from 860 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
122 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 421779.27
Deduct 0 from 60 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.

On to step 12:
600 divided by 122 is 4 with a remainder of 112.
The next digit of our result is 4. 
Result so far: 421779.2704
Deduct 488 from 600 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 13:
The number 122 fits into 1120 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 421779.27049
Subtracting 1098 from 1120 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
When dividing 220 by 122, we get 1 with a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 421779.270491
The remainder is 98 after subtracting 122 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 15:
The number 122 fits into 980 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 421779.2704918
If we take 976 away from 980, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 16:
122 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 421779.2704918
If we take 0 away from 40, 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.

After the division, we end up with 421779.2704918 and a remainder of 4e-08.
