We look at the division of 79701522 by 646 
We want to divide 79701522 by 646.

Step 1:
The number 646 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 646

On to step 2:
646 goes into 79 0 times with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Append the next digit (7) from the dividend to 79 and continue with: 797 / 646

On to step 3:
646 goes into 797 1 times with a remainder of 151.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 646 away from 797, we end up with 151.
Append the next digit (0) from the dividend to 151 and continue with: 1510 / 646

On to step 4:
The number 646 fits into 1510 2 times, leaving a remainder of 218.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1292 away from 1510, we end up with 218.
Append the next digit (1) from the dividend to 218 and continue with: 2181 / 646

On to step 5:
When dividing 2181 by 646, we get 3 with a remainder of 243.
The next digit of our result is 3. 
Result so far: 123.0
Deduct 1938 from 2181 and we're left with 243.
Take the next digit (5) from the dividend and append it to 243, then repeat: 2435 / 646

Moving on to step 6:
2435 divided by 646 is 3 with a remainder of 497.
Record the quotient 3 as the next digit in the result. 
Result so far: 1233.0
If we subtract 1938 from 2435, we get 497.
Grab the next digit (2) from the dividend, add it to 497, then carry on: 4972 / 646

Step 7:
The number 646 fits into 4972 7 times, leaving a remainder of 450.
Record the quotient 7 as the next digit in the result. 
Result so far: 12337.0
If we subtract 4522 from 4972, we get 450.
Grab the next digit (2) from the dividend, add it to 450, then carry on: 4502 / 646

Advancing to step 8:
646 goes into 4502 6 times with a remainder of 626.
The number 6 becomes the next digit in our result. 
Result so far: 123376.0
Deduct 3876 from 4502 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

On to step 9:
If we divide 6260 by 646, we get 9 and a remainder of 446.
Record the quotient 9 as the next digit in the result. 
Result so far: 123376.9
If we take 5814 away from 6260, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 10:
When dividing 4460 by 646, we get 6 with a remainder of 584.
Record the quotient 6 as the next digit in the result. 
Result so far: 123376.96
If we subtract 3876 from 4460, we get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 11:
646 goes into 5840 9 times with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 123376.969
Deduct 5814 from 5840 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
When dividing 260 by 646, we get 0 with a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 123376.969
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 13:
When dividing 2600 by 646, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 123376.96904
Deduct 2584 from 2600 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
646 goes into 160 0 times with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 123376.96904
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 15:
When dividing 1600 by 646, we get 2 with a remainder of 308.
Record the quotient 2 as the next digit in the result. 
Result so far: 123376.9690402
The remainder is 308 after subtracting 1292 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 16:
When dividing 3080 by 646, we get 4 with a remainder of 496.
Write down 4 as next digit of the result. 
Result so far: 123376.96904024
The remainder is 496 after subtracting 2584 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

The final outcome is 123376.96904024, with a leftover of 4.96e-07.
