We look at the division of 52011853 by 641 
We want to figure out the number of times 52011853 can be divided by 641.

Step 1:
When dividing 5 by 641, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 641

Going ahead to step 2:
If we divide 52 by 641, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 641

Advancing to step 3:
The number 641 fits into 520 0 times, leaving a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 520, we get 520.
Include the next digit (1) from the dividend after 520, then repeat: 5201 / 641

Let's proceed to step 4:
641 can be fit into 5201 8 times, resulting in a remainder of 73.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 5128 from 5201 leaves us with 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 641

Advancing to step 5:
The number 641 fits into 731 1 times, leaving a remainder of 90.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtract 641 from 731 to get 90.
Fetch the next digit (8) from the dividend, attach it to 90 and continue: 908 / 641

On to step 6:
641 can be fit into 908 1 times, resulting in a remainder of 267.
Write down 1 as next digit of the result. 
Result so far: 811.0
If we take 641 away from 908, we end up with 267.
Include the next digit (5) from the dividend after 267, then repeat: 2675 / 641

Advancing to step 7:
2675 divided by 641 is 4 with a remainder of 111.
Use 4 as the next digit of our solution. 
Result so far: 8114.0
Subtract 2564 from 2675 to get 111.
Append the next digit (3) from the dividend to 111 and continue with: 1113 / 641

Let's proceed to step 8:
641 goes into 1113 1 times with a remainder of 472.
Record the quotient 1 as the next digit in the result. 
Result so far: 81141.0
Subtracting 641 from 1113 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 9:
The number 641 fits into 4720 7 times, leaving a remainder of 233.
The number 7 becomes the next digit in our result. 
Result so far: 81141.7
Subtract 4487 from 4720 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 10:
641 can be fit into 2330 3 times, resulting in a remainder of 407.
Record the quotient 3 as the next digit in the result. 
Result so far: 81141.73
The remainder is 407 after subtracting 1923 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Step 11:
4070 divided by 641 is 6 with a remainder of 224.
Use 6 as the next digit of our solution. 
Result so far: 81141.736
Subtracting 3846 from 4070 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.

Going ahead to step 12:
641 can be fit into 2240 3 times, resulting in a remainder of 317.
Put 3 as the next digit of the answer. 
Result so far: 81141.7363
If we subtract 1923 from 2240, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 13:
The number 641 fits into 3170 4 times, leaving a remainder of 606.
The next digit of our result is 4. 
Result so far: 81141.73634
If we subtract 2564 from 3170, we get 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Let's proceed to step 14:
If we divide 6060 by 641, we get 9 and a remainder of 291.
Record the quotient 9 as the next digit in the result. 
Result so far: 81141.736349
Subtract 5769 from 6060 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 15:
The number 641 fits into 2910 4 times, leaving a remainder of 346.
The next digit of our result is 4. 
Result so far: 81141.7363494
If we subtract 2564 from 2910, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 16:
3460 divided by 641 is 5 with a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 81141.73634945
If we take 3205 away from 3460, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Our division results in 81141.73634945 with a remaining 2.55e-07.
