4200504 ÷ 751 
We want to figure out the number of times 4200504 can be divided by 751.

Step 1:
The number 751 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 751

Moving on to step 2:
If we divide 42 by 751, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 751

Let's proceed to step 3:
The number 751 fits into 420 0 times, leaving a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 420 and we're left with 420.
Grab the next digit (0) from the dividend, add it to 420, then carry on: 4200 / 751

Going ahead to step 4:
If we divide 4200 by 751, we get 5 and a remainder of 445.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 3755 away from 4200, we end up with 445.
Grab the next digit (5) from the dividend, add it to 445, then carry on: 4455 / 751

Advancing to step 5:
751 can be fit into 4455 5 times, resulting in a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
The remainder is 700 after subtracting 3755 from 4455.
Take the next digit (0) from the dividend and append it to 700, then repeat: 7000 / 751

On to step 6:
When dividing 7000 by 751, we get 9 with a remainder of 241.
Use 9 as the next digit of our solution. 
Result so far: 559.0
Deduct 6759 from 7000 and we're left with 241.
Take the next digit (4) from the dividend and append it to 241, then repeat: 2414 / 751

Going ahead to step 7:
If we divide 2414 by 751, we get 3 and a remainder of 161.
The number 3 becomes the next digit in our result. 
Result so far: 5593.0
If we subtract 2253 from 2414, we get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 8:
When dividing 1610 by 751, we get 2 with a remainder of 108.
Write down 2 as next digit of the result. 
Result so far: 5593.2
If we subtract 1502 from 1610, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 9:
If we divide 1080 by 751, we get 1 and a remainder of 329.
Put 1 as the next digit of the answer. 
Result so far: 5593.21
Subtract 751 from 1080 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Step 10:
When dividing 3290 by 751, we get 4 with a remainder of 286.
Put 4 as the next digit of the answer. 
Result so far: 5593.214
If we subtract 3004 from 3290, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 11:
2860 divided by 751 is 3 with a remainder of 607.
Put 3 as the next digit of the answer. 
Result so far: 5593.2143
Subtracting 2253 from 2860 leaves us with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Step 12:
751 goes into 6070 8 times with a remainder of 62.
The next digit of our result is 8. 
Result so far: 5593.21438
If we subtract 6008 from 6070, 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.

Step 13:
If we divide 620 by 751, we get 0 and a remainder of 620.
The next digit of our result is 0. 
Result so far: 5593.21438
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.

On to step 14:
751 can be fit into 6200 8 times, resulting in a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 5593.2143808
If we take 6008 away from 6200, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 15:
751 can be fit into 1920 2 times, resulting in a remainder of 418.
The next digit of our result is 2. 
Result so far: 5593.21438082
The remainder is 418 after subtracting 1502 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Our division results in 5593.21438082 with a remaining 4.18e-07.
