81556189 ÷ 427 
We want to divide 81556189 by 427.

Advancing to step 1:
The number 427 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 427

Step 2:
The number 427 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 427

Step 3:
The number 427 fits into 815 1 times, leaving a remainder of 388.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 427 from 815 to get 388.
Bring next digit (5) of the dividend behind the 388 and repeat the process: 3885 / 427

Going ahead to step 4:
The number 427 fits into 3885 9 times, leaving a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 3843 away from 3885, we end up with 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 427

Moving on to step 5:
427 can be fit into 426 0 times, resulting in a remainder of 426.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Subtracting 0 from 426 leaves us with 426.
Fetch the next digit (1) from the dividend, attach it to 426 and continue: 4261 / 427

Step 6:
4261 divided by 427 is 9 with a remainder of 418.
Use 9 as the next digit of our solution. 
Result so far: 1909.0
Subtract 3843 from 4261 to get 418.
Take the next digit (8) from the dividend and append it to 418, then repeat: 4188 / 427

Advancing to step 7:
The number 427 fits into 4188 9 times, leaving a remainder of 345.
The number 9 becomes the next digit in our result. 
Result so far: 19099.0
Deduct 3843 from 4188 and we're left with 345.
Grab the next digit (9) from the dividend, add it to 345, then carry on: 3459 / 427

On to step 8:
427 goes into 3459 8 times with a remainder of 43.
The next digit of our result is 8. 
Result so far: 190998.0
The remainder is 43 after subtracting 3416 from 3459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
The number 427 fits into 430 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 190998.1
Deduct 427 from 430 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
The number 427 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 190998.1
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
The number 427 fits into 300 0 times, leaving a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 190998.1
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 190998.1, and the remainder is 0.03.
