72778125 ÷ 126 
We want to divide 72778125 by 126.

Advancing to step 1:
The number 126 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 126

Going ahead to step 2:
If we divide 72 by 126, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (7) from the dividend to 72 and continue with: 727 / 126

Let's proceed to step 3:
727 divided by 126 is 5 with a remainder of 97.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 630 from 727 leaves us with 97.
Grab the next digit (7) from the dividend, add it to 97, then carry on: 977 / 126

On to step 4:
126 can be fit into 977 7 times, resulting in a remainder of 95.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we subtract 882 from 977, we get 95.
Bring next digit (8) of the dividend behind the 95 and repeat the process: 958 / 126

Let's proceed to step 5:
958 divided by 126 is 7 with a remainder of 76.
The number 7 becomes the next digit in our result. 
Result so far: 577.0
Subtract 882 from 958 to get 76.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 126

Going ahead to step 6:
The number 126 fits into 761 6 times, leaving a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 5776.0
Subtract 756 from 761 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 126

Advancing to step 7:
126 goes into 52 0 times with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 57760.0
If we take 0 away from 52, we end up with 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 126

Advancing to step 8:
126 can be fit into 525 4 times, resulting in a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 577604.0
Subtract 504 from 525 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
210 divided by 126 is 1 with a remainder of 84.
The number 1 becomes the next digit in our result. 
Result so far: 577604.1
Deduct 126 from 210 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 10:
When dividing 840 by 126, we get 6 with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 577604.16
If we subtract 756 from 840, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
The number 126 fits into 840 6 times, leaving a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 577604.166
Deduct 756 from 840 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 577604.166 with a remaining 0.0084.
