We look at the division of 374639 by 91 
We want to figure out the number of times 374639 can be divided by 91.

Step 1:
The number 91 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 91

Moving on to step 2:
91 can be fit into 37 0 times, resulting in a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 91

Going ahead to step 3:
91 goes into 374 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 364 away from 374, we end up with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 91

On to step 4:
91 goes into 106 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtract 91 from 106 to get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 91

On to step 5:
91 goes into 153 1 times with a remainder of 62.
The next digit of our result is 1. 
Result so far: 411.0
If we take 91 away from 153, we end up with 62.
Take the next digit (9) from the dividend and append it to 62, then repeat: 629 / 91

Let's proceed to step 6:
91 goes into 629 6 times with a remainder of 83.
The next digit of our result is 6. 
Result so far: 4116.0
Deduct 546 from 629 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 7:
91 goes into 830 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 4116.9
Deduct 819 from 830 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
110 divided by 91 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 4116.91
The remainder is 19 after subtracting 91 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
91 can be fit into 190 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4116.912
The remainder is 8 after subtracting 182 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
When dividing 80 by 91, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 4116.912
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
If we divide 800 by 91, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 4116.91208
If we take 728 away from 800, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
720 divided by 91 is 7 with a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 4116.912087
If we take 637 away from 720, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 13:
When dividing 830 by 91, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 4116.9120879
Subtracting 819 from 830 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
If we divide 110 by 91, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 4116.91208791
If we subtract 91 from 110, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 4116.91208791, with a leftover of 1.9e-08.
