10123521 ÷ 238 
We want to divide 10123521 by 238.

Advancing to step 1:
238 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 238

Step 2:
238 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 238

Let's proceed to step 3:
238 can be fit into 101 0 times, resulting in a remainder of 101.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 101 after subtracting 0 from 101.
Take the next digit (2) from the dividend and append it to 101, then repeat: 1012 / 238

Going ahead to step 4:
238 can be fit into 1012 4 times, resulting in a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 952 from 1012 leaves us with 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 238

Step 5:
The number 238 fits into 603 2 times, leaving a remainder of 127.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 476 from 603 and we're left with 127.
Fetch the next digit (5) from the dividend, attach it to 127 and continue: 1275 / 238

Step 6:
If we divide 1275 by 238, we get 5 and a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 425.0
Subtract 1190 from 1275 to get 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 238

Going ahead to step 7:
If we divide 852 by 238, we get 3 and a remainder of 138.
Put 3 as the next digit of the answer. 
Result so far: 4253.0
If we subtract 714 from 852, we get 138.
Take the next digit (1) from the dividend and append it to 138, then repeat: 1381 / 238

Moving on to step 8:
1381 divided by 238 is 5 with a remainder of 191.
Write down 5 as next digit of the result. 
Result so far: 42535.0
Deduct 1190 from 1381 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Going ahead to step 9:
When dividing 1910 by 238, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 42535.8
Deduct 1904 from 1910 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
If we divide 60 by 238, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 42535.8
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
238 can be fit into 600 2 times, resulting in a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 42535.802
If we take 476 away from 600, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 12:
238 can be fit into 1240 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 42535.8025
If we take 1190 away from 1240, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
238 goes into 500 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 42535.80252
If we take 476 away from 500, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 238 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 42535.802521
If we subtract 238 from 240, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 15:
238 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 42535.802521
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 16:
200 divided by 238 is 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 42535.802521
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 42535.802521, with a leftover of 2e-07.
