We're dividing 42246972 by 746 
We want to figure out the number of times 42246972 can be divided by 746.

On to step 1:
If we divide 4 by 746, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 746

Moving on to step 2:
746 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 746

Step 3:
The number 746 fits into 422 0 times, leaving a remainder of 422.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 422 leaves us with 422.
Take the next digit (4) from the dividend and append it to 422, then repeat: 4224 / 746

Going ahead to step 4:
4224 divided by 746 is 5 with a remainder of 494.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 3730 from 4224 to get 494.
Take the next digit (6) from the dividend and append it to 494, then repeat: 4946 / 746

Let's proceed to step 5:
If we divide 4946 by 746, we get 6 and a remainder of 470.
The next digit of our result is 6. 
Result so far: 56.0
Deduct 4476 from 4946 and we're left with 470.
Include the next digit (9) from the dividend after 470, then repeat: 4709 / 746

Step 6:
4709 divided by 746 is 6 with a remainder of 233.
Record the quotient 6 as the next digit in the result. 
Result so far: 566.0
Deduct 4476 from 4709 and we're left with 233.
Append the next digit (7) from the dividend to 233 and continue with: 2337 / 746

On to step 7:
When dividing 2337 by 746, we get 3 with a remainder of 99.
The number 3 becomes the next digit in our result. 
Result so far: 5663.0
The remainder is 99 after subtracting 2238 from 2337.
Append the next digit (2) from the dividend to 99 and continue with: 992 / 746

Going ahead to step 8:
746 goes into 992 1 times with a remainder of 246.
The next digit of our result is 1. 
Result so far: 56631.0
Subtracting 746 from 992 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 9:
746 can be fit into 2460 3 times, resulting in a remainder of 222.
Put 3 as the next digit of the answer. 
Result so far: 56631.3
Subtract 2238 from 2460 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 10:
When dividing 2220 by 746, we get 2 with a remainder of 728.
The next digit of our result is 2. 
Result so far: 56631.32
Subtracting 1492 from 2220 leaves us with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Moving on to step 11:
The number 746 fits into 7280 9 times, leaving a remainder of 566.
Use 9 as the next digit of our solution. 
Result so far: 56631.329
The remainder is 566 after subtracting 6714 from 7280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 12:
If we divide 5660 by 746, we get 7 and a remainder of 438.
The next digit of our result is 7. 
Result so far: 56631.3297
If we take 5222 away from 5660, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 13:
746 goes into 4380 5 times with a remainder of 650.
Write down 5 as next digit of the result. 
Result so far: 56631.32975
The remainder is 650 after subtracting 3730 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 14:
746 can be fit into 6500 8 times, resulting in a remainder of 532.
The number 8 becomes the next digit in our result. 
Result so far: 56631.329758
Subtract 5968 from 6500 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Let's proceed to step 15:
5320 divided by 746 is 7 with a remainder of 98.
The next digit of our result is 7. 
Result so far: 56631.3297587
Deduct 5222 from 5320 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 16:
746 goes into 980 1 times with a remainder of 234.
The next digit of our result is 1. 
Result so far: 56631.32975871
Deduct 746 from 980 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The final result is 56631.32975871 with a remainder of 2.34e-07.
