We're dividing 70221581 by 666 
We want to divide 70221581 by 666.

Going ahead to step 1:
If we divide 7 by 666, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 666

Let's proceed to step 2:
666 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 666

Advancing to step 3:
702 divided by 666 is 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 666 from 702 leaves us with 36.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 666

Going ahead to step 4:
The number 666 fits into 362 0 times, leaving a remainder of 362.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 362 to get 362.
Grab the next digit (1) from the dividend, add it to 362, then carry on: 3621 / 666

On to step 5:
666 goes into 3621 5 times with a remainder of 291.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
The remainder is 291 after subtracting 3330 from 3621.
Bring next digit (5) of the dividend behind the 291 and repeat the process: 2915 / 666

Step 6:
The number 666 fits into 2915 4 times, leaving a remainder of 251.
Write down 4 as next digit of the result. 
Result so far: 1054.0
Deduct 2664 from 2915 and we're left with 251.
Bring next digit (8) of the dividend behind the 251 and repeat the process: 2518 / 666

Going ahead to step 7:
666 goes into 2518 3 times with a remainder of 520.
Use 3 as the next digit of our solution. 
Result so far: 10543.0
Deduct 1998 from 2518 and we're left with 520.
Append the next digit (1) from the dividend to 520 and continue with: 5201 / 666

Moving on to step 8:
The number 666 fits into 5201 7 times, leaving a remainder of 539.
Put 7 as the next digit of the answer. 
Result so far: 105437.0
The remainder is 539 after subtracting 4662 from 5201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Moving on to step 9:
When dividing 5390 by 666, we get 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 105437.8
Subtract 5328 from 5390 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
666 can be fit into 620 0 times, resulting in a remainder of 620.
Write down 0 as next digit of the result. 
Result so far: 105437.8
Subtract 0 from 620 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 11:
666 can be fit into 6200 9 times, resulting in a remainder of 206.
Use 9 as the next digit of our solution. 
Result so far: 105437.809
Deduct 5994 from 6200 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 12:
If we divide 2060 by 666, we get 3 and a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 105437.8093
If we subtract 1998 from 2060, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
666 goes into 620 0 times with a remainder of 620.
Write down 0 as next digit of the result. 
Result so far: 105437.8093
Subtracting 0 from 620 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 14:
666 goes into 6200 9 times with a remainder of 206.
Use 9 as the next digit of our solution. 
Result so far: 105437.809309
Subtract 5994 from 6200 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 15:
666 goes into 2060 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 105437.8093093
If we take 1998 away from 2060, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 16:
666 goes into 620 0 times with a remainder of 620.
Record the quotient 0 as the next digit in the result. 
Result so far: 105437.8093093
Deduct 0 from 620 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

The quotient of the division is 105437.8093093, and the remainder is 6.2e-07.
