43221321 divided by 749 
We're looking to find how many times 749 goes into 43221321.

Moving on to step 1:
When dividing 4 by 749, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 749

Advancing to step 2:
If we divide 43 by 749, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 749

Step 3:
749 can be fit into 432 0 times, resulting in a remainder of 432.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 432 and we're left with 432.
Bring next digit (2) of the dividend behind the 432 and repeat the process: 4322 / 749

Moving on to step 4:
When dividing 4322 by 749, we get 5 with a remainder of 577.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 3745 from 4322 to get 577.
Take the next digit (1) from the dividend and append it to 577, then repeat: 5771 / 749

On to step 5:
749 goes into 5771 7 times with a remainder of 528.
The next digit of our result is 7. 
Result so far: 57.0
Subtract 5243 from 5771 to get 528.
Take the next digit (3) from the dividend and append it to 528, then repeat: 5283 / 749

Let's proceed to step 6:
5283 divided by 749 is 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 577.0
Subtracting 5243 from 5283 leaves us with 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 749

Going ahead to step 7:
The number 749 fits into 402 0 times, leaving a remainder of 402.
Use 0 as the next digit of our solution. 
Result so far: 5770.0
The remainder is 402 after subtracting 0 from 402.
Grab the next digit (1) from the dividend, add it to 402, then carry on: 4021 / 749

Going ahead to step 8:
4021 divided by 749 is 5 with a remainder of 276.
The number 5 becomes the next digit in our result. 
Result so far: 57705.0
Deduct 3745 from 4021 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 9:
The number 749 fits into 2760 3 times, leaving a remainder of 513.
Use 3 as the next digit of our solution. 
Result so far: 57705.3
The remainder is 513 after subtracting 2247 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Step 10:
The number 749 fits into 5130 6 times, leaving a remainder of 636.
Put 6 as the next digit of the answer. 
Result so far: 57705.36
Subtracting 4494 from 5130 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 11:
749 can be fit into 6360 8 times, resulting in a remainder of 368.
Use 8 as the next digit of our solution. 
Result so far: 57705.368
Subtract 5992 from 6360 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 12:
The number 749 fits into 3680 4 times, leaving a remainder of 684.
Write down 4 as next digit of the result. 
Result so far: 57705.3684
Deduct 2996 from 3680 and we're left with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Going ahead to step 13:
The number 749 fits into 6840 9 times, leaving a remainder of 99.
Write down 9 as next digit of the result. 
Result so far: 57705.36849
The remainder is 99 after subtracting 6741 from 6840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 14:
749 goes into 990 1 times with a remainder of 241.
The next digit of our result is 1. 
Result so far: 57705.368491
Deduct 749 from 990 and we're left with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 15:
749 can be fit into 2410 3 times, resulting in a remainder of 163.
Write down 3 as next digit of the result. 
Result so far: 57705.3684913
The remainder is 163 after subtracting 2247 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 16:
749 can be fit into 1630 2 times, resulting in a remainder of 132.
Put 2 as the next digit of the answer. 
Result so far: 57705.36849132
If we subtract 1498 from 1630, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

After the division, we end up with 57705.36849132 and a remainder of 1.32e-07.
