51390133 divided by 561 
Our goal is to divide 51390133 by 561.

Advancing to step 1:
When dividing 5 by 561, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 561

Going ahead to step 2:
When dividing 51 by 561, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 561

Moving on to step 3:
The number 561 fits into 513 0 times, leaving a remainder of 513.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 513 and we're left with 513.
Take the next digit (9) from the dividend and append it to 513, then repeat: 5139 / 561

On to step 4:
5139 divided by 561 is 9 with a remainder of 90.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 5049 from 5139, we get 90.
Take the next digit (0) from the dividend and append it to 90, then repeat: 900 / 561

Step 5:
If we divide 900 by 561, we get 1 and a remainder of 339.
The next digit of our result is 1. 
Result so far: 91.0
Subtracting 561 from 900 leaves us with 339.
Append the next digit (1) from the dividend to 339 and continue with: 3391 / 561

Advancing to step 6:
If we divide 3391 by 561, we get 6 and a remainder of 25.
The next digit of our result is 6. 
Result so far: 916.0
Subtracting 3366 from 3391 leaves us with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 561

Going ahead to step 7:
253 divided by 561 is 0 with a remainder of 253.
Put 0 as the next digit of the answer. 
Result so far: 9160.0
Subtracting 0 from 253 leaves us with 253.
Grab the next digit (3) from the dividend, add it to 253, then carry on: 2533 / 561

On to step 8:
561 goes into 2533 4 times with a remainder of 289.
Write down 4 as next digit of the result. 
Result so far: 91604.0
Subtract 2244 from 2533 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 9:
If we divide 2890 by 561, we get 5 and a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 91604.5
If we take 2805 away from 2890, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
When dividing 850 by 561, we get 1 with a remainder of 289.
The number 1 becomes the next digit in our result. 
Result so far: 91604.51
Deduct 561 from 850 and we're left with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 11:
561 goes into 2890 5 times with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 91604.515
The remainder is 85 after subtracting 2805 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 12:
561 goes into 850 1 times with a remainder of 289.
Write down 1 as next digit of the result. 
Result so far: 91604.5151
The remainder is 289 after subtracting 561 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Going ahead to step 13:
If we divide 2890 by 561, we get 5 and a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 91604.51515
Deduct 2805 from 2890 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 14:
561 goes into 850 1 times with a remainder of 289.
Use 1 as the next digit of our solution. 
Result so far: 91604.515151
If we take 561 away from 850, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 15:
The number 561 fits into 2890 5 times, leaving a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 91604.5151515
Subtract 2805 from 2890 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 16:
If we divide 850 by 561, we get 1 and a remainder of 289.
Record the quotient 1 as the next digit in the result. 
Result so far: 91604.51515151
Subtracting 561 from 850 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Our division results in 91604.51515151 with a remaining 2.89e-07.
