72035151 ÷ 521 
We want to divide 72035151 by 521.

Advancing to step 1:
7 divided by 521 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 521

Advancing to step 2:
521 can be fit into 72 0 times, resulting in a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 521

Moving on to step 3:
If we divide 720 by 521, we get 1 and a remainder of 199.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 521 from 720 to get 199.
Take the next digit (3) from the dividend and append it to 199, then repeat: 1993 / 521

Going ahead to step 4:
521 goes into 1993 3 times with a remainder of 430.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1563 away from 1993, we end up with 430.
Include the next digit (5) from the dividend after 430, then repeat: 4305 / 521

Moving on to step 5:
If we divide 4305 by 521, we get 8 and a remainder of 137.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
Deduct 4168 from 4305 and we're left with 137.
Append the next digit (1) from the dividend to 137 and continue with: 1371 / 521

Let's proceed to step 6:
521 can be fit into 1371 2 times, resulting in a remainder of 329.
Use 2 as the next digit of our solution. 
Result so far: 1382.0
Subtracting 1042 from 1371 leaves us with 329.
Grab the next digit (5) from the dividend, add it to 329, then carry on: 3295 / 521

Moving on to step 7:
If we divide 3295 by 521, we get 6 and a remainder of 169.
Use 6 as the next digit of our solution. 
Result so far: 13826.0
If we subtract 3126 from 3295, we get 169.
Grab the next digit (1) from the dividend, add it to 169, then carry on: 1691 / 521

Moving on to step 8:
If we divide 1691 by 521, we get 3 and a remainder of 128.
The number 3 becomes the next digit in our result. 
Result so far: 138263.0
Subtract 1563 from 1691 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 9:
521 can be fit into 1280 2 times, resulting in a remainder of 238.
Record the quotient 2 as the next digit in the result. 
Result so far: 138263.2
The remainder is 238 after subtracting 1042 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 10:
2380 divided by 521 is 4 with a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 138263.24
If we take 2084 away from 2380, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 11:
If we divide 2960 by 521, we get 5 and a remainder of 355.
Use 5 as the next digit of our solution. 
Result so far: 138263.245
If we subtract 2605 from 2960, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 12:
The number 521 fits into 3550 6 times, leaving a remainder of 424.
Use 6 as the next digit of our solution. 
Result so far: 138263.2456
If we take 3126 away from 3550, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 13:
The number 521 fits into 4240 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 138263.24568
If we take 4168 away from 4240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
720 divided by 521 is 1 with a remainder of 199.
The next digit of our result is 1. 
Result so far: 138263.245681
The remainder is 199 after subtracting 521 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 15:
1990 divided by 521 is 3 with a remainder of 427.
The number 3 becomes the next digit in our result. 
Result so far: 138263.2456813
Subtract 1563 from 1990 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Advancing to step 16:
When dividing 4270 by 521, we get 8 with a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 138263.24568138
If we subtract 4168 from 4270, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The quotient of the division is 138263.24568138, and the remainder is 1.02e-07.
