We divide 87773812 by 406
We want to divide 87773812 by 406.

Advancing to step 1:
The number 406 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 406

Advancing to step 2:
406 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Grab the next digit (7) from the dividend, add it to 87, then carry on: 877 / 406

Advancing to step 3:
877 divided by 406 is 2 with a remainder of 65.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 812 from 877 and we're left with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 406

Going ahead to step 4:
657 divided by 406 is 1 with a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 406 away from 657, we end up with 251.
Take the next digit (3) from the dividend and append it to 251, then repeat: 2513 / 406

Moving on to step 5:
If we divide 2513 by 406, we get 6 and a remainder of 77.
The next digit of our result is 6. 
Result so far: 216.0
If we subtract 2436 from 2513, we get 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 406

Going ahead to step 6:
778 divided by 406 is 1 with a remainder of 372.
The next digit of our result is 1. 
Result so far: 2161.0
If we take 406 away from 778, we end up with 372.
Take the next digit (1) from the dividend and append it to 372, then repeat: 3721 / 406

On to step 7:
406 goes into 3721 9 times with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 21619.0
Deduct 3654 from 3721 and we're left with 67.
Take the next digit (2) from the dividend and append it to 67, then repeat: 672 / 406

Going ahead to step 8:
406 can be fit into 672 1 times, resulting in a remainder of 266.
The next digit of our result is 1. 
Result so far: 216191.0
If we take 406 away from 672, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 9:
406 goes into 2660 6 times with a remainder of 224.
Use 6 as the next digit of our solution. 
Result so far: 216191.6
Subtracting 2436 from 2660 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 10:
406 goes into 2240 5 times with a remainder of 210.
The next digit of our result is 5. 
Result so far: 216191.65
If we subtract 2030 from 2240, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 11:
If we divide 2100 by 406, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 216191.655
If we subtract 2030 from 2100, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 216191.655, with a leftover of 0.007.
