Let's divide 940091 by 51
We want to figure out the number of times 940091 can be divided by 51.

Step 1:
If we divide 9 by 51, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 51

On to step 2:
51 can be fit into 94 1 times, resulting in a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 51 from 94 leaves us with 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 51

Advancing to step 3:
51 goes into 430 8 times with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 408 away from 430, we end up with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 51

On to step 4:
The number 51 fits into 220 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
Deduct 204 from 220 and we're left with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 51

Going ahead to step 5:
51 goes into 169 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 1843.0
If we take 153 away from 169, we end up with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 51

Going ahead to step 6:
The number 51 fits into 161 3 times, leaving a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 18433.0
If we take 153 away from 161, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 51, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 18433.1
Subtracting 51 from 80 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
51 can be fit into 290 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 18433.15
Deduct 255 from 290 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
350 divided by 51 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 18433.156
Deduct 306 from 350 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
If we divide 440 by 51, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 18433.1568
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
If we divide 320 by 51, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 18433.15686
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
140 divided by 51 is 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 18433.156862
Deduct 102 from 140 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
The number 51 fits into 380 7 times, leaving a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 18433.1568627
The remainder is 23 after subtracting 357 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
51 can be fit into 230 4 times, resulting in a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 18433.15686274
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 18433.15686274 and a remainder of 2.6e-08.
