We look at the division of 64531102 by 141 
We want to figure out the number of times 64531102 can be divided by 141.

On to step 1:
141 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 141

On to step 2:
If we divide 64 by 141, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 141

Step 3:
When dividing 645 by 141, we get 4 with a remainder of 81.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 564 from 645 leaves us with 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 141

On to step 4:
If we divide 813 by 141, we get 5 and a remainder of 108.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
The remainder is 108 after subtracting 705 from 813.
Append the next digit (1) from the dividend to 108 and continue with: 1081 / 141

On to step 5:
141 goes into 1081 7 times with a remainder of 94.
The next digit of our result is 7. 
Result so far: 457.0
Deduct 987 from 1081 and we're left with 94.
Include the next digit (1) from the dividend after 94, then repeat: 941 / 141

Going ahead to step 6:
If we divide 941 by 141, we get 6 and a remainder of 95.
Use 6 as the next digit of our solution. 
Result so far: 4576.0
Subtracting 846 from 941 leaves us with 95.
Bring next digit (0) of the dividend behind the 95 and repeat the process: 950 / 141

Going ahead to step 7:
If we divide 950 by 141, we get 6 and a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 45766.0
If we subtract 846 from 950, we get 104.
Grab the next digit (2) from the dividend, add it to 104, then carry on: 1042 / 141

On to step 8:
141 can be fit into 1042 7 times, resulting in a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 457667.0
Deduct 987 from 1042 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 9:
141 can be fit into 550 3 times, resulting in a remainder of 127.
Put 3 as the next digit of the answer. 
Result so far: 457667.3
If we subtract 423 from 550, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 10:
When dividing 1270 by 141, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 457667.39
The remainder is 1 after subtracting 1269 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
141 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 457667.39
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 141, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 457667.39
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 457667.39, and the remainder is 0.001.
