We divide 42195421 by 786
We want to figure out the number of times 42195421 can be divided by 786.

Advancing to step 1:
4 divided by 786 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 786

On to step 2:
42 divided by 786 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 786

Step 3:
786 goes into 421 0 times with a remainder of 421.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 421 after subtracting 0 from 421.
Fetch the next digit (9) from the dividend, attach it to 421 and continue: 4219 / 786

Advancing to step 4:
786 goes into 4219 5 times with a remainder of 289.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 3930 from 4219 leaves us with 289.
Take the next digit (5) from the dividend and append it to 289, then repeat: 2895 / 786

Advancing to step 5:
If we divide 2895 by 786, we get 3 and a remainder of 537.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtracting 2358 from 2895 leaves us with 537.
Fetch the next digit (4) from the dividend, attach it to 537 and continue: 5374 / 786

Going ahead to step 6:
5374 divided by 786 is 6 with a remainder of 658.
Use 6 as the next digit of our solution. 
Result so far: 536.0
If we take 4716 away from 5374, we end up with 658.
Bring next digit (2) of the dividend behind the 658 and repeat the process: 6582 / 786

Advancing to step 7:
786 goes into 6582 8 times with a remainder of 294.
The number 8 becomes the next digit in our result. 
Result so far: 5368.0
Deduct 6288 from 6582 and we're left with 294.
Include the next digit (1) from the dividend after 294, then repeat: 2941 / 786

Advancing to step 8:
2941 divided by 786 is 3 with a remainder of 583.
The number 3 becomes the next digit in our result. 
Result so far: 53683.0
The remainder is 583 after subtracting 2358 from 2941.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Going ahead to step 9:
5830 divided by 786 is 7 with a remainder of 328.
The number 7 becomes the next digit in our result. 
Result so far: 53683.7
Subtract 5502 from 5830 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 10:
When dividing 3280 by 786, we get 4 with a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 53683.74
Deduct 3144 from 3280 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 11:
The number 786 fits into 1360 1 times, leaving a remainder of 574.
The next digit of our result is 1. 
Result so far: 53683.741
Deduct 786 from 1360 and we're left with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

On to step 12:
5740 divided by 786 is 7 with a remainder of 238.
The next digit of our result is 7. 
Result so far: 53683.7417
Deduct 5502 from 5740 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 13:
The number 786 fits into 2380 3 times, leaving a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 53683.74173
The remainder is 22 after subtracting 2358 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
220 divided by 786 is 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 53683.74173
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 15:
The number 786 fits into 2200 2 times, leaving a remainder of 628.
Put 2 as the next digit of the answer. 
Result so far: 53683.7417302
Deduct 1572 from 2200 and we're left with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 16:
When dividing 6280 by 786, we get 7 with a remainder of 778.
Use 7 as the next digit of our solution. 
Result so far: 53683.74173027
The remainder is 778 after subtracting 5502 from 6280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

After the division, we end up with 53683.74173027 and a remainder of 7.78e-07.
