We look at the division of 87133123 by 408 
Our goal is to divide 87133123 by 408.

Advancing to step 1:
8 divided by 408 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 408

Moving on to step 2:
408 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Grab the next digit (1) from the dividend, add it to 87, then carry on: 871 / 408

Going ahead to step 3:
871 divided by 408 is 2 with a remainder of 55.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 55 after subtracting 816 from 871.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 408

On to step 4:
553 divided by 408 is 1 with a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 408 away from 553, we end up with 145.
Append the next digit (3) from the dividend to 145 and continue with: 1453 / 408

Moving on to step 5:
1453 divided by 408 is 3 with a remainder of 229.
Write down 3 as next digit of the result. 
Result so far: 213.0
If we take 1224 away from 1453, we end up with 229.
Append the next digit (1) from the dividend to 229 and continue with: 2291 / 408

On to step 6:
2291 divided by 408 is 5 with a remainder of 251.
Record the quotient 5 as the next digit in the result. 
Result so far: 2135.0
If we take 2040 away from 2291, we end up with 251.
Bring next digit (2) of the dividend behind the 251 and repeat the process: 2512 / 408

Let's proceed to step 7:
408 can be fit into 2512 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 21356.0
Subtract 2448 from 2512 to get 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 408

Advancing to step 8:
When dividing 643 by 408, we get 1 with a remainder of 235.
Use 1 as the next digit of our solution. 
Result so far: 213561.0
Subtracting 408 from 643 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 9:
408 goes into 2350 5 times with a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 213561.5
Subtracting 2040 from 2350 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 10:
If we divide 3100 by 408, we get 7 and a remainder of 244.
The number 7 becomes the next digit in our result. 
Result so far: 213561.57
If we subtract 2856 from 3100, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 11:
When dividing 2440 by 408, we get 5 with a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 213561.575
The remainder is 400 after subtracting 2040 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 12:
408 goes into 4000 9 times with a remainder of 328.
Put 9 as the next digit of the answer. 
Result so far: 213561.5759
Deduct 3672 from 4000 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 13:
408 can be fit into 3280 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 213561.57598
If we subtract 3264 from 3280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
The number 408 fits into 160 0 times, leaving a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 213561.57598
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
The number 408 fits into 1600 3 times, leaving a remainder of 376.
Write down 3 as next digit of the result. 
Result so far: 213561.5759803
If we take 1224 away from 1600, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 16:
408 goes into 3760 9 times with a remainder of 88.
Put 9 as the next digit of the answer. 
Result so far: 213561.57598039
If we take 3672 away from 3760, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 213561.57598039 with a remainder of 8.8e-08.
