The next digit of our result is 7. 
Result so far: 7.0
If we subtract 4753 from 5122, we get 369.
Include the next digit (9) from the dividend after 369, then repeat: 3699 / 679

Advancing to step 5:
3699 divided by 679 is 5 with a remainder of 304.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we subtract 3395 from 3699, we get 304.
Take the next digit (3) from the dividend and append it to 304, then repeat: 3043 / 679

Moving on to step 6:
679 goes into 3043 4 times with a remainder of 327.
The next digit of our result is 4. 
Result so far: 754.0
Subtracting 2716 from 3043 leaves us with 327.
Append the next digit (0) from the dividend to 327 and continue with: 3270 / 679

On to step 7:
679 goes into 3270 4 times with a remainder of 554.
Put 4 as the next digit of the answer. 
Result so far: 7544.0
The remainder is 554 after subtracting 2716 from 3270.
Append the next digit (6) from the dividend to 554 and continue with: 5546 / 679

Advancing to step 8:
If we divide 5546 by 679, we get 8 and a remainder of 114.
The number 8 becomes the next digit in our result. 
Result so far: 75448.0
Subtract 5432 from 5546 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 9:
679 goes into 1140 1 times with a remainder of 461.
Use 1 as the next digit of our solution. 
Result so far: 75448.1
The remainder is 461 after subtracting 679 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

On to step 10:
When dividing 4610 by 679, we get 6 with a remainder of 536.
Record the quotient 6 as the next digit in the result. 
Result so far: 75448.16
Subtracting 4074 from 4610 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 11:
If we divide 5360 by 679, we get 7 and a remainder of 607.
The number 7 becomes the next digit in our result. 
Result so far: 75448.167
The remainder is 607 after subtracting 4753 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Moving on to step 12:
If we divide 6070 by 679, we get 8 and a remainder of 638.
Put 8 as the next digit of the answer. 
Result so far: 75448.1678
Subtracting 5432 from 6070 leaves us with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Going ahead to step 13:
The number 679 fits into 6380 9 times, leaving a remainder of 269.
Write down 9 as next digit of the result. 
Result so far: 75448.16789
If we subtract 6111 from 6380, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 14:
When dividing 2690 by 679, we get 3 with a remainder of 653.
Put 3 as the next digit of the answer. 
Result so far: 75448.167893
Deduct 2037 from 2690 and we're left with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Advancing to step 15:
679 goes into 6530 9 times with a remainder of 419.
Put 9 as the next digit of the answer. 
Result so far: 75448.1678939
Deduct 6111 from 6530 and we're left with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 16:
4190 divided by 679 is 6 with a remainder of 116.
Record the quotient 6 as the next digit in the result. 
Result so far: 75448.16789396
If we take 4074 away from 4190, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final outcome is 75448.16789396, with a leftover of 1.16e-07.
