We're dividing 78429738 by 931 
We want to divide 78429738 by 931.

Going ahead to step 1:
If we divide 7 by 931, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 931

Advancing to step 2:
When dividing 78 by 931, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 931

Let's proceed to step 3:
The number 931 fits into 784 0 times, leaving a remainder of 784.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 784, we end up with 784.
Fetch the next digit (2) from the dividend, attach it to 784 and continue: 7842 / 931

Moving on to step 4:
If we divide 7842 by 931, we get 8 and a remainder of 394.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 394 after subtracting 7448 from 7842.
Append the next digit (9) from the dividend to 394 and continue with: 3949 / 931

Step 5:
931 can be fit into 3949 4 times, resulting in a remainder of 225.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtracting 3724 from 3949 leaves us with 225.
Fetch the next digit (7) from the dividend, attach it to 225 and continue: 2257 / 931

On to step 6:
931 goes into 2257 2 times with a remainder of 395.
Record the quotient 2 as the next digit in the result. 
Result so far: 842.0
Subtract 1862 from 2257 to get 395.
Bring next digit (3) of the dividend behind the 395 and repeat the process: 3953 / 931

Let's proceed to step 7:
3953 divided by 931 is 4 with a remainder of 229.
Use 4 as the next digit of our solution. 
Result so far: 8424.0
Deduct 3724 from 3953 and we're left with 229.
Fetch the next digit (8) from the dividend, attach it to 229 and continue: 2298 / 931

Moving on to step 8:
The number 931 fits into 2298 2 times, leaving a remainder of 436.
Write down 2 as next digit of the result. 
Result so far: 84242.0
The remainder is 436 after subtracting 1862 from 2298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 9:
The number 931 fits into 4360 4 times, leaving a remainder of 636.
Use 4 as the next digit of our solution. 
Result so far: 84242.4
Deduct 3724 from 4360 and we're left 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.

Going ahead to step 10:
If we divide 6360 by 931, we get 6 and a remainder of 774.
Record the quotient 6 as the next digit in the result. 
Result so far: 84242.46
The remainder is 774 after subtracting 5586 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Moving on to step 11:
If we divide 7740 by 931, we get 8 and a remainder of 292.
The number 8 becomes the next digit in our result. 
Result so far: 84242.468
Subtract 7448 from 7740 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 12:
931 goes into 2920 3 times with a remainder of 127.
Put 3 as the next digit of the answer. 
Result so far: 84242.4683
If we take 2793 away from 2920, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 13:
1270 divided by 931 is 1 with a remainder of 339.
Use 1 as the next digit of our solution. 
Result so far: 84242.46831
Subtracting 931 from 1270 leaves us with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Step 14:
3390 divided by 931 is 3 with a remainder of 597.
Use 3 as the next digit of our solution. 
Result so far: 84242.468313
Deduct 2793 from 3390 and we're left with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Step 15:
931 goes into 5970 6 times with a remainder of 384.
Record the quotient 6 as the next digit in the result. 
Result so far: 84242.4683136
Deduct 5586 from 5970 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 16:
The number 931 fits into 3840 4 times, leaving a remainder of 116.
The next digit of our result is 4. 
Result so far: 84242.46831364
The remainder is 116 after subtracting 3724 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The quotient of the division is 84242.46831364, and the remainder is 1.16e-07.
