We look at the division of 30720143 by 526 
We want to divide 30720143 by 526.

Step 1:
The number 526 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 526

Moving on to step 2:
If we divide 30 by 526, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 526

Moving on to step 3:
The number 526 fits into 307 0 times, leaving a remainder of 307.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 307, we get 307.
Fetch the next digit (2) from the dividend, attach it to 307 and continue: 3072 / 526

Step 4:
3072 divided by 526 is 5 with a remainder of 442.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 2630 from 3072 to get 442.
Bring next digit (0) of the dividend behind the 442 and repeat the process: 4420 / 526

Advancing to step 5:
When dividing 4420 by 526, we get 8 with a remainder of 212.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Deduct 4208 from 4420 and we're left with 212.
Fetch the next digit (1) from the dividend, attach it to 212 and continue: 2121 / 526

Step 6:
The number 526 fits into 2121 4 times, leaving a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 584.0
Subtract 2104 from 2121 to get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 526

On to step 7:
When dividing 174 by 526, we get 0 with a remainder of 174.
The next digit of our result is 0. 
Result so far: 5840.0
The remainder is 174 after subtracting 0 from 174.
Grab the next digit (3) from the dividend, add it to 174, then carry on: 1743 / 526

Advancing to step 8:
526 goes into 1743 3 times with a remainder of 165.
Use 3 as the next digit of our solution. 
Result so far: 58403.0
Deduct 1578 from 1743 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 9:
If we divide 1650 by 526, we get 3 and a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 58403.3
The remainder is 72 after subtracting 1578 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
When dividing 720 by 526, we get 1 with a remainder of 194.
Use 1 as the next digit of our solution. 
Result so far: 58403.31
Subtract 526 from 720 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 11:
526 can be fit into 1940 3 times, resulting in a remainder of 362.
Put 3 as the next digit of the answer. 
Result so far: 58403.313
Subtract 1578 from 1940 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 12:
If we divide 3620 by 526, we get 6 and a remainder of 464.
The number 6 becomes the next digit in our result. 
Result so far: 58403.3136
Deduct 3156 from 3620 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 13:
526 goes into 4640 8 times with a remainder of 432.
The next digit of our result is 8. 
Result so far: 58403.31368
The remainder is 432 after subtracting 4208 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 14:
When dividing 4320 by 526, we get 8 with a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 58403.313688
If we take 4208 away from 4320, we end up 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.

The final outcome is 58403.313688, with a leftover of 1.12e-05.
