72438803 ÷ 856 
We want to figure out the number of times 72438803 can be divided by 856.

Going ahead to step 1:
The number 856 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 856

Going ahead to step 2:
72 divided by 856 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 856

Moving on to step 3:
856 goes into 724 0 times with a remainder of 724.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 724 to get 724.
Bring next digit (3) of the dividend behind the 724 and repeat the process: 7243 / 856

Moving on to step 4:
When dividing 7243 by 856, we get 8 with a remainder of 395.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6848 from 7243 to get 395.
Take the next digit (8) from the dividend and append it to 395, then repeat: 3958 / 856

Advancing to step 5:
If we divide 3958 by 856, we get 4 and a remainder of 534.
The next digit of our result is 4. 
Result so far: 84.0
Subtract 3424 from 3958 to get 534.
Fetch the next digit (8) from the dividend, attach it to 534 and continue: 5348 / 856

Going ahead to step 6:
The number 856 fits into 5348 6 times, leaving a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 846.0
Subtracting 5136 from 5348 leaves us with 212.
Append the next digit (0) from the dividend to 212 and continue with: 2120 / 856

Going ahead to step 7:
2120 divided by 856 is 2 with a remainder of 408.
Record the quotient 2 as the next digit in the result. 
Result so far: 8462.0
Subtracting 1712 from 2120 leaves us with 408.
Append the next digit (3) from the dividend to 408 and continue with: 4083 / 856

Advancing to step 8:
If we divide 4083 by 856, we get 4 and a remainder of 659.
Record the quotient 4 as the next digit in the result. 
Result so far: 84624.0
If we subtract 3424 from 4083, we get 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Let's proceed to step 9:
6590 divided by 856 is 7 with a remainder of 598.
The next digit of our result is 7. 
Result so far: 84624.7
The remainder is 598 after subtracting 5992 from 6590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

On to step 10:
5980 divided by 856 is 6 with a remainder of 844.
Write down 6 as next digit of the result. 
Result so far: 84624.76
The remainder is 844 after subtracting 5136 from 5980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Moving on to step 11:
When dividing 8440 by 856, we get 9 with a remainder of 736.
Write down 9 as next digit of the result. 
Result so far: 84624.769
The remainder is 736 after subtracting 7704 from 8440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Advancing to step 12:
7360 divided by 856 is 8 with a remainder of 512.
Use 8 as the next digit of our solution. 
Result so far: 84624.7698
The remainder is 512 after subtracting 6848 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 13:
5120 divided by 856 is 5 with a remainder of 840.
Record the quotient 5 as the next digit in the result. 
Result so far: 84624.76985
If we subtract 4280 from 5120, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

On to step 14:
If we divide 8400 by 856, we get 9 and a remainder of 696.
The next digit of our result is 9. 
Result so far: 84624.769859
Subtract 7704 from 8400 to get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Moving on to step 15:
If we divide 6960 by 856, we get 8 and a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 84624.7698598
Subtract 6848 from 6960 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 16:
856 can be fit into 1120 1 times, resulting in a remainder of 264.
The number 1 becomes the next digit in our result. 
Result so far: 84624.76985981
Deduct 856 from 1120 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Our division results in 84624.76985981 with a remaining 2.64e-07.
